Curious as to what could cause a global outage like that. The system consists of birds in the air and individual ground stations. There's no big choke point that I'm aware of that could cause the whole shebang to go dark. Am I missing something here?

BGP is the canonical way to take your entire global network offline within seconds. Glancing at BGP looking glasses, Starlink's prefixes seem to still be announced, but there could still be an accidental blackhole or routing loop within their AS, or something broken in one of their transit providers.

No idea if that's what's going on, but routing protocols are one of a few effectively global control planes that can go wrong very quickly like this.

If it were BGP/routing, you would think we'd be able to still get a signal and the modem would think it's healthy (although maybe not if the issue prevented us from obtaining our public IP), we just wouldn't be able to route to any dst. In the current case we don't have a signal (orange light on the modem)

Yes, before the drop out my traffic was coming from a downlink station in Bulgaria, on an IP on AS14593

Traceroute from "the internet" back to that IP reaches AS14593 just fine, and my endpoint doesn't get beyond the first hop of the local starlink router.

Whatever it is, it doesn't look like a peering problem

From various monitoring points I have on multiple internet connections.

One of the promises of starlink was it would stay in space as long as possible before being downlinked, giving far lower latency, alas that hasn't happened yet, and traffic will run thousands of miles in the wrong direction before being downlinked. For example from one location to another I have 360ms via Starlink but just 200ms rtt via local provision (5g p2p wireless then optical). On another it used to downlink in Lagos, but now it downlinks in Nairobi, meaning traffic to Lagos routes Nairobi -> Marseille -> Lagos, taking far longer than it used to. A shame really.

Re:Starlink is currently experiencing a service outage. Our ... by dave_universetf on Thursday July 24, 2025 @04:25PM (#44675627)
Does the orange light specifically mean no RF link at all? Or does it include anything that prevents the modem from getting an IP address and route configuration? If the latter, BGP could still be at fault if it took out access to the control planes on the ground. But again all just guessing, from the outside all I see is the BGP routes are still being announced, and everyone seems to be seeing 100% packet loss and zero traffic.
Re:Starlink is currently experiencing a service outage. Our ... by indigodaddy on Thursday July 24, 2025 @04:34PM (#44675768)
Right, good point that could be the case, those were just my assumptions and probably jumping to conclusions on my part speculating that orange means no signal (don't actually have any idea :) ). Imagine it could be any of what you said too.

I rebooted my terminal and I can’t tell for sure if it sees any satellites. It looks like it doesn't.

It says it didn’t, and it says the “which way is down” thing hasn’t converged. Occasionally, the signal to noise ratio light in the app goes gray which means < 3.

It also rebooted itself.

Before the first reboot, 30% of pings went through. It’s almost like the azimuth or some other timely but cached data was corrupted.

  Starlink VP of engineering Michael Nicolls tweeted that the service has "now mostly recovered from the network outage" after two and a half hours.

  "The outage was due to failure of key internal software services that operate the core network. We apologize for the temporary disruption in our service; we are deeply committed to providing a highly reliable network, and will fully root cause this issue and ensure it does not occur again," the tweet, posted at 3:23 p.m. PT, says.

Almost always. Most people look at global networks like black magic and don’t realize this.

For most large businesses, 90%+ of major network events are caused by internally-driven network config changes.

Depending on how far along the business is towards automation, a proportion of the 90% can be attributed to a human going “off script” - I.e.: making a change that had not been reviewed.

They still have tons of ground-based infrastructure that has all the regular failure modes. I suspect the satellites also route IP traffic statically, and they only do so to a fixed set of ground gateways all operated by Starlink (compared to e.g. Iridium, which makes in-space switching decisions and can at least continue ongoing phone calls between two devices without actually needing a reachable ground gateway).

National telcos manage to take themselves out countrywide from time to time too, so I'd assume the same usual suspects apply: Routing problems, botched global configuration changes etc.

If anything, due to centralization, ubiquitous and effectively free connectivity, and centralization/automation of configuration changes, the blast radius of any given error or malicious action has probably been steadily increasing over the years.

You would expect to be able to at least connect to a satellite unless the satellite has no Internet connection so it does not make itself available to be connected to you.

Anyone have any deeper knowledge about this for the curious?
