Re:Tell HN: Cloudflare's D1 service degraded since 2 days on Saturday January 24, 2026 @10:42AM (#46744488)
I have been praising Cloudflare up and down over the past year. As a software programmer, I rarely want to care about DevOps bikeshedding to get my applications up and running.

So after having used GCP, AWS, and all the orchestration baggage that came with it, developing and testing user-facing apps with Miniflare, workerd, D1, and wrangler has been a breeze... until I discovered some of my D1 calls take 20 seconds to resolve on a table with 10 rows. Query takes sub-millisecond.

Status page looking good, all systems operational. Digging through issues, pulling my hair out. Then stumbled upon this post to discover there is indeed an issue, and it is acknowledged on Discord... Discord? Why?

Honestly, I've been the fool here. Discouraged every single soul I know from vendor lock-in, only to vendor lock-in myself because I really liked the product.

Cloudflare is in a great position to dominate the ecosystem. They understand our needs. However, feature creep, half-baked releases, and improper communication don't give me the confidence to continue using their services at scale.

Incident is marked as resolved... tracing outliers tell a different story. Guess it's time to move on. Can't claim you offer a reliable database at scale if a trivial lookup on a 10-row table resolves in 20 seconds.

Hey there!

My name is Koray. I’ve been programming since I was ten years old, starting with computer magazines. It quickly turned into my career, and I've had the opportunity to work in various companies since I was 16.

Eight years ago, at the age of 23, I started my first company. Since then, I've been involved in different roles, primarily focusing on technical product leadership and cross-platform application development. Some of the products I have built and helped build have been embraced by millions of users, received awards, and consistently maintained high rankings on app stores.

Recently, my latest pursuit came to an end due to funding constraints. Now, I'm excited to explore new opportunities where I can wear different hats. I'm open to any industry and I'm technology-agnostic.

I love learning new things and have a wide range of interests, including 3D printing, IoT, and home automation. On a fun note, I also collect vinyls, synthesizers and groove boxes.

If there is a match, let's chat!
