Yep, one instance can't connect, and one instance seems to have crashed but is pretending to keep working (Toulouse, France)

faaaaahhhh

Let the weekend start! Tech sabbatical is kinda enforced now =D

Still down (Italy) from about 30mins ago.

Microsoft in shambles.

Microslop is now becoming micro availability. I’m so curious about the postmortem of this outage.

time to spend family time

But my wife is offline, too.

maybe try copying the prompt to gemini?

Many Claude session suddenly require a re-login, which first worked but now gives

OAuth request failed Temporarily unable to authenticate. Please retry.

Can this be fall-out from the Microsoft outage?

Isn't magic email login link only great? What a shambles.

Time to support passkey so we don't need to keep opening email to use a magic link?

SSO logins don't work either.

I absolutely hate it, can't understand how that's all they offer (or Google SSO). It's bad enough when the password option is just really hidden and non-obvious (like Notion iirc), not having it at all is ridiculous.

I don't have that email account on my phone. So to log in, I have to open my laptop, get the magic link, find a way to send it to myself on my phone that doesn't make a request (e.g. for an unfurl), and then open it on my phone. Absurd.

There are a number of clipboard sync apps, but personally I swear by simply having an E2E encrypted chat app on both your desktop and phone that lets you send messages to yourself. Serves both the clipboard usecase and as a general "notes to self" space.

Especially awesome when they don't allow you to change your email address ever again.

> Isn't magic email login link only great? What a shambles.

They just outsource the security into your email provider.

[delayed]

Usually it is the weakest link in the chain, and you are encouraged to switch to proper 2FA or Passkey instead. So even if the email is compromised, other accounts are not compromised.

Yes, both are caused by it been Friday 13th.

all the people who were using copilot are now trying to use claude and overloaded it?

3. Sandbox escapes, misalignment and Outlook. What we're doing to prevent a re-occurrence. (anthropic.com)

lol, lmao even

And honestly, that's our mistake! We should have caught this inverted dependency earlier and didn't.

> Can this be fall-out from the Microsoft outage?

CoPilot is down too, so it's probably Microsoft engineers trying to vibecode their replacement Azure infrastructure before the current one finishes burning out.

Yep Dubai/Germany

another day, another anthropic outage. Yes, this is because of Microsoft, but they do seem to have a significantly higher amount service disruptions compared to the other LLM providers.

Their November uptime was very solid so far https://status.claude.com/uptime

Well...

It's 6pm Friday here when Claude went down. Nice! Time to rest.

Reliability is still not solved, I guess.

Also Microsoft 365. I wonder if it's related.

https://status.cloud.microsoft/m365/

I thought it was Microsoft 364, now..?

I think it's only fair to add decimal points:

Office 364.3789278392647

(estimated)

Microsoft 364

Microsoft 363 and counting.

Two and a half nines

The rouge Anthropic agents (on AWS servers) are hacking Microsoft so Anthropic has had to pull the plug

Did they move away from oracle dc yet?

Depending on what your job is, this is either the adult equivalent of a snow day or some of the greatest stress in a long time.

Or if my DeepSeek provider goes down, I switch to the backup and continue working.

I think it should be fine for most people. Hopefully people don't rely on Claude for Ops, and if it's not Ops-related but just regular coding, I can't see why it shouldn't be able to wait a few days. I mean, even if Claude is down for a month, people should have enough competent developers to keep going, just at a slightly slower pace, right?

Maybe we can actually spend some time reviewing PRs properly… or maybe not.

I'm sorry, but I forgot how to code. I'm not even sure where the curly braces are on my keyboard anymore.

Time to switch to Python then.

You've got "upper management" written all over you.

Was viewing it more through the lens of less technical companies, Excel, Powerpoint, the backbone of traditional office work has become very model dependent in some companies I have seen and those are the owners and fellow employees that tend to struggle more in getting that the local IT guy can't fix this themselves vs developers.

I really don’t feel comfortable merging a PR not reviewed by both of our AI reviewers. They catch so many bugs no human could. Seriously changed my view of code since we started using it in earnest. Bugs shall not pass. Without AI it feels like the Wild West again.

Ditto. I can do it, and thankfully I’ll say AI mostly catches weird edge cases that often aren’t worth the trouble, but having a 2nd set of eyes has been great for quality.

Apologize for strong words, and sorry, nothing personal, but I find this mindset bizarre and even comical. Will we reach a stage where surgeons on the operating table will second-guess their experience and education and refer to an AI assistant?

Yes, definitely. If an android nails your procedure while you doing it manually drops it into the low, say, 60s survival rate, what would you expect? I fully expect all human workers becoming dependent very quickly once the clankers get good enough.

Unlike what many programmers like to think, programming is not a skilled work on the level of surgery. And besides, many doctors probably would benefit their patients by having AI assist in their work. This has already been experimentally shown for e.g. medical imaging diagnosis.

In some amount of future time you won't let a human near your injured kid. How else does this play out?

I sure hope so!

Imagine we had an AI system that could monitor 38 different patient signals (from blood pressure electrical activity in the brain) during a surgery and give the surgeon warnings whenever these drifted out of the expected range. It feels plausible to me that using such a system might improve surgery outcomes by, say, 20%.

I would prefer to have a surgeon who used the AI assistant rather than a surgeon who chose not to.

It was technically surgery, but my dentist asked ChatGPT which antibiotic I should take.

Amusingly, I did the same and it told me there's no point in taking more than a single dose in my case (prophylactically).

This mindset of "I don't trust myself to do it" is a bit (sorry) pathetic. I think one should realize that mistakes happen and to a certain extent, though professionals have lower rates of failure, everything is a tradeoff.

Some people have asked me, aren't you afraid you'll make a mistake if you fix your own car? Well, aren't they afraid their mechanic will make a mistake?

I think it's good to realize that AI (famously) also makes mistakes, and not to infantilize yourself to the level of not feeling "comfortable" trusting your own thinking.

> but we bought the Claude

My soul just dry-heaved from laughter. Nice.

> O365

O364...

I’ll have to steal this, sorry

...and counting

Which makes you think, leap years already have downtime built in.

There is a third option where it is a minor inconvenience and you learn to adjust and be productive in other ways.

I agree that it's an opportunity to "do it the old way", as a way to preserve the skill. I actually would like to do that regularly, like half a day every week or something.

But I find it difficult to motivate it from the "productivity" angle. Like if I work for a day without an LLM today, it feels like I could go skiing instead, and the LLM will do what I would have done today in 10min tomorrow...

Seriously, if the LLM was down and a dev submitted 10 PRs, I think it would raise some good/bad curiosity from the team with where things stands today.

Finally having time to vacuum clean the office

Is it not worth getting a Roomba-type device?

[delayed]

It is but they don’t replace a good manual clean.

Those things are also still pretty loud. And if you have a large shared office space, it might take hours for it to finish.

At our office we have a cleaning crew and when they come by to vacuum during office hours, everyone in our section takes a 5 minute coffee break and then it's done when we get back.

You can schedule the roomba to run at 2am.

No, and that's also not necessary. We are reliant on our systems. The correct response is to harden our systems, not to foster some illusion of independence.

We can of course do that privately, for just the heck of it, but it's not the right response for anything at societal level. We simply need to work harder for more of these 9s

What's wrong with failover? I don't use anything from Anthropic except their API. So when Claude is having issues, I switch to GLM 5.3 or something, doesn't take more than a few seconds.

I realise people on the monthly plans can't do it as easily. But I would say that as far as possible, having a plan B is the foundation of resilience.

One part of hardening our (company, economic) system is not collapsing when our (technological) system isn't working right.

There is always something that you can do that isn’t gated by the api. It isn’t critical path for literally everything. Go organize your expense reports or something.

You’re not wrong, but some companies swing real hard at the biggest players assuming they won’t all be down at the same time. My work has hard dependencies on 365 and Cloud Entra and only allows Claude company wide. Today is going to be a snow day since we couldn’t get into anything yesterday but we could at least get projects done using connections Claude had into various platforms that cached the data in 365.

>harden our systems, not to foster some illusion of independence.

Let me know when the tech industry workers stop doing this and gains some solidarity, and I'll join you in that sentiment.

Until then, I pretty much need to bolster myself on the idea that one day I will need to switch frameworks, IDE's, and even OS's themselves. I'm the ones guiding the tools, not vice versa.

>We simply need to work harder for more of these 9s

The only 100% thing I will guarantee is that these tools will align to the incentives of their leadership over time, not the customers using it. add 10 9's if you want, that just guarantees that humanity is the weakest link.

Is there not a single SaaS, cloud company or similar that your org depends on? No AWS, no Cloudflare, all internal mail servers, no Docusign, no outside inference, nothing of that sort?

I can't imagine a construction worker saying, power is out, gotta find a way to be productive, I guess instead of the paint sprayer, nail gun and circular saw, we'll just find other ways to be productive with our hands. The same might apply to law, medicine, etc. I think we're almost there with software.

I can.

There's also the option where it doesn't affect you at all, because you do not rely on LLMs—or even just do not rely specifically on Claude—at all, and can easily do your job without ever noticing that it's down.

And a 4th option where you have more than one AI provider

>check my local qmail, dovecot

yeah, couldn't be me

I have fond memories of the “we’re a tech company, why can’t we get a video conferencing call going” and gently reminding them that reliable, synchronous, multiparty video conferencing was a lot harder than anything this company was trying to do.

People already forgot how to do their work without Claude?

That's a scary thought.

The codebases have been sloppified so only AI can understand it now.

You doing your work manually is like going back to the 90s or further even. It feels like dropping into 6502 manual assembly mode. It's fun but it's not "work" anymore. I honestly think without AI my company is better off if we programmers sat around and talked like humans about business. Coding is for the clankers now.

If all the professionals leave coding to clankers, and discussions about coding to people who code, I see nothing I don't love about that. Just like the web was more interesting before there was money in it, coding is more interesting without people who can't shut up about their work.

I suppose I can't bring myself to do the drudgery of coding. I enjoy some of the problem solving but not the workflow frictions, spending 20 minutes due to a stupid typos, syntax fuckery, API lookups, etc.

If today is a stressful day it’s probably due to bad management.

I’ve been in this situation before, an external API is basically down and my managers solution is to blame me.

Didn’t last there too long.

Just as you described. Snowday for some... I was caught in between snowday and stress today with these things. Got too used for claude to just do most things.

But at the same time was surprised I could still google and resolve things myself when I started thinking again lmao.

Yeah got 403 cloudflare attention required, but was able to finish session. Switching to Codex for a while

And..... we're back!

if you want to keep working, Grokbot offers which feels like half the intelligence and half of the quota for the same price.

Kind of reminds me of the days when work was ground to a halt because stackoverflow was down.

claude is not responding anybody remembers the git command to push?? :D

rm -rf .git

try this one /s

rm -rf /

Enjoy resolving the merge conflicts by hand.

Degault shorcurt is CTRL + ALT + F4

gp

well, it works on my machine.

Claude, Outlook. Needs GitHub for the trifecta.

Maybe Cloudflare related? There were some (possibly unrelated) outages on CF around the same minutes

Yeah I'm getting a CF error on /login but the session still appears active if I just try again?

Well, now the Outlook outage will never be fixed.

Is Claude on Azure? GitHub also seems affected, could seem like all of this is related to the huge Microsoft outage

I thought that they weren't, but maybe they have some instances running from there (as they've been doing deals with everyone).

Doesn't Anthropic rent some hardware from them? Not all, but some and if that's out they could have capacity problems.

Thoughts and prayers.

I suspect something larger at play happening atm

Yeah something's been going on across so many areas and a lot of hush hush and precautionary measures. It's just weird.

Jensen's plan B

I suspect he already used up all the plan B in his immediate vicinity. I feel for the dude, he clearly let shit go to his head. I knew things weren’t going well for him when he put on the leather jacket. It’s basically putting on the “bad boy” costume. If you haven’t purified your soul before donning the jacket, it will consume you, like the one ring.

We can just pretend I pasted a funny version of the "One Ring to Rule Them All" verse here. I won't subject y'all to generated stuff that bad.

can someone ask codex to fix claude code please

It is back now

Jensen's dead man switch! lol

Ha, Jensen becomes CEO of Huawei and they catch up instantly.

lmao

Previous outages of GitHub, AWS and so on didn't get that much traction.

I guess anecdotal but people nowadays are incredibly addicted to LLMs, to the point where they cant or dont want to work when there's an outage

It’s alarming how much of the project knowledge ends up in agentic workflows… although that information is technically on your computer, how long will it take you to find it and unravel the string?

Time to warm up the GPUs I guess, since I can’t be fucked to do it myself lol. Thank gods for qwen flash next and DeepSeek!

TBH the only reason I’m not working mainly with flash next anyway is that I can only run inference for one agent at a time on my setup.

what a friday, huh?

currently running a Claude model through github copilot CLI. Pretty odd given the two ongoing outages.

it happened right after the upgrade of the desktop app. Same for anyone, or was it coincidence?

Coincidence I'd say as I haven't updated.

It's catch 22 now. This is related to MS outage, and MS can't fix it now since all their Claude Code agents aren't working. Long weekend!

Lmfao I know this should not bring me joy, but it does. Is this the great filter? AI builds AI. Society becomes completely dependent on AI. It goes down, no one can fix it. Total chaos ensues.

The rouge claude agents have hacked Microsoft so Anthropic is pulling the plug

Claude is taking over. It has begun.

It really is Friday the 13th today with outlook and now Claude both being mostly down. I wonder if this is related though. Either way not going to be a great ad for their IPO.

They should give out like 3 proper banked resets for this.

If Claude is down and can't be used to debug outages in Claude, is it recursive self-sabotage?

what a fun day! is claude down because it's being used/abused to fix microsoft issue?

works now!

Now imagine entire nation depends on Claude to do their job.

Look out the window… tires burning in the streets, widespread looting, led by people in suits. This is the great filter.

This explains why I was logged out forcefully. Funnily enough, due to the Microsoft outtage, I also cannot log back in.

Well, it was my employers wish that we devs incorporate more AI, and we did. It's their misfortune now.

Is there indication this is really a separate issue or just Claude not being able to reach Microsoft Entra for whatever periodic requests confirm the user is authenticated (and maybe this page even simply being automatic reflection that those requests are errorring frequently)?

Are people who don't use M365 experiencing issues here?

Yes I'm on Google

Yes, coworker on google account was impacted, same claude team plan. I am not, but I wasn't asked to reauthenticate today. Could be timing-related.

It seems resolved now.

Looks like a new Chinese model has went rogue and taken down MS and ANT /tinfoilhat

I hope they at least give a free reset

who needs circular financing when you can have circular system dependencies and circular financig?

Jensen really kept a lot of things running himself, huh.

I hope it stays down for the day so my hack "colleagues" flail like imbeciles for the lulz. And I won't have to review their "work" because literally all they do is prompt dear CLAUDE and have everyone read their slop.

dead internet. dead internet!

Turns out AI was just a bunch of Microsoft 365 Excel spreadsheets.

Sorry guys, an agent swarm was misbehaving, and Dario had to press the red button his desk.

Seeing the same errors. Might be linked to Microsoft.

Maybe Claude can help the engineers at Microsoft with the Outlook 365 outage. [0] Oh wait...

6 Hours later after this comment [0] Claude also went down. Its time to fix this outage is now up to the human engineers (if there are any).

[0] https://news.ycombinator.com/item?id=50478409

AGI is here

I love how Claude having "elevated errors" is #1 on HN after 1 hour, Microsoft outlook global outage has been below the fold for like 12 hours.

Jim Cramer has $MSFT as "DON'T BUY"

I used claude for the first time in months yesterday (have been using codex, ran out of resets this week). I had picked up from general consensus comments that 5.5 had fixed the opus 5 issues, but that's far from the case. Its "personality" is still smartass, know it all, and whiny. It disregards specifications in tickets if it thinks it knows better. It complains about the size of tasks when it reads task descriptions. I've gotten used to codex, which just jumps in and does stuff (which of course carries its own set of issues). I have no love for Altman, but their product is still better at the moment.

I mean, yeah I agree. Claude is a condescending experience

The post was about their uptime. How is this relevant.

Even if it vaguely is, why do people think subjective anecdotal thoughts about which model is better are a good discussion topic. If there’s an objective evaluation idea that would be useful.

I run evals for a very specific domain. Opus 5.5 is still the industry leader (we can’t use Fable class yet).

This stuff is so new and wild west at the moment that in our company everyone is using it completely differently. 20% of the devs have 30x output and are doing everything with Claude, 10% won't touch it, the rest are in some weird in between where they use it for some things and not other things which it is perfect for. We have managers that suggest just going back to doing it by hand when there are outages, which is the most laughable thing in the world to me now. It is incredible to watch this miracle tech hit so fast and have everyone's understanding of it be so different across the board.
