Given the amount of usage I'm now getting from Opus 5.5, I'm surprised it took this long since release for their first outage. In my experience, it's about 10x the usage of Fable 5.1 with similar, perhaps greater levels of intelligence.

just a hunch, but i think they might just provide an update as soon as possible.
Maybe an increase in sign ups due to people learning of their existence from the IPO? It's the authentication that seems to be failing, not the actual inference.

Anthropic yesterday: We have perfect AI agents to do everything now, value us at $100 Trillion
Anthropic today: We don't really have AI agents, they are glorified versions of automation scripts and one has broken today. But tomorrow we will have perfect AI agents, so still value us at $100 Trillion.
I've seen many people with 500s for over an hour, meanwhile the status page was green with no issues whatsoever.
Have they tried using a fraction of their immense budget to run E2E tests?
At this point downdetector is more reliable than any of these "status" pages. And it does show reports starting 9:30ish AM EST.
I've been getting 503s from the API. When I first checked everything was green, then it said "Claude.ai (including the desktop and mobile apps), Claude Code and Claude Cowork" and I see now they've included the API in the failure as well
Yesterday got email from Claude that they are offering 50% off for one month if I renew my subscription. I bought it today and now this. I wonder if they sent that email to too many people.
Imagine having a bunch of Claude agents doing time sensitive work and this happens and now a single human needs to pick up several 8k PRs authored by bots that can't talk to you now. Not sure how effective it would be to switch models using OpenRouter and the like given that, as the Earendil guys said, there is a lot of session detail that the provider doesn't share. The uptime is really going to cap their market penetration imo.
Berget's "Cached input tokens are billed at the same rate as regular input tokens" pricing model is kind of painful for lots of coding use-cases, especially when competitors are offering significant discounts for cached input tokens.
Project completely disappeared. Conveniently for Anthropic, the bug report also went down, so they weren't spammed by my stale complaints after the project magically resurfaced.
Too many OpenAI $200 customers switching over to Anthropic.

Yeah, Fable 5.1 just seems Pareto-dominated. Opus 5.5 is the first model that feels like a step change for me, personally since like 4.6
Exactly, 5.5 is the first model that I used that's better than 4.6.
Fable5.1 is Speedy

Someone put update-status-page.pl in a one minute cron job.

Yeah I had a session fail and keep failing.

Coding may have been solved, but uptime remains a mystery.

Maybe show respect to OpenAI DevDay

can't you say the say with imagine "power goes out" or the "internet goes out"?
(but yes if AI is going to propagate, they need to fix their uptimes)
They probably have an OpenAI subscription, same for OpenAI SWE, they have a Claude Code subscription
Berget Code is running normal https://berget.ai/code

If I can't use it I just sit there. That's the fallback now.
The auto mode classifier has been out of service more than once in last 24 hours.
Had to shift+tab into other modes and manually approve permissions like a cave man

Why can they simply not add more computer?

Claude outages are now the new go outside and touch grass indicator
Previous: GitHub outage
Oh come on, I just had my weekly limit reset.
Hey, it's 99.9 if you look at it upside down.
Uptime of the Beast
Claude, deploy to prod - make no mistakes!
A usage reset would be a much appreciated apology. :)
