I honestly feel like it's more honest status measure than many status pages I know.

This is not an outage, Claude just gets lazier on Fridays. Sometimes Claude wants more lunch breaks, takes a half day and leaves the desk early just like any human would. (since AI boosters like comparing LLMs to humans all the time) /s

They seem to be a victim of their own success. Their response times are quite bad, and it's widely believed they are doing something to degrade service quality (quantizing?) in order to stretch resources. They just announced that they're cutting their usage limits down during peak hours as well. They're in serious risk of losing their lead with this sort of performance.

You can access Claude models with Google Cloud reliability via VertexAI. The caveat is that you cannot use your subscription, per-token pricing only. I personally prefer per-token, it makes you more thoughtful about your setup and usage, instead of spray and pray. You can also access the notable open weight models with VertexAI, only need to change the model id string.

Remember when putting your entire life & business into the cloud was good because they were all offering 5 9s of uptime? Very few cases these days.. feels like we are lucky to get 2 9s anymore.

We had a ton of traffic coming in to check them: https://downforeveryoneorjustme.com/anthropic Not one of the usual ones that has service problems :)

At this point you can stop worrying about downtime-free deployments so the devops becomes easier

Victim of success. They are the best. ChatGPT is walmart. Gemini is kroger. Claude is... idk your local grocer that is always amazing and costs more?

I wonder how much is due to supply constraints, how much is standard growing pains, and if over-reliance on AI was the cause for any outages.

MAKE NO MISTAKES! DO NOT HALLUCINATE! FIX IT!

Probably vide-coded their infrastructure

I wouldn't be too harsh, scaling x10 YoY is a bit hard on the infra!

If you don't pay attention 99% may sound high but it means up to 20 hours of downtime in over the quarter. Anthropic has had more than that. Yikes.

Maybe they are gunning for 5 nines (9.9999%)

Hey folks, I'm Alex from the reliability engineering team at Anthropic. We've just posted the retrospective for this incident: > On March 26–27, 2026, customers experienced elevated error rates when using Claude Opus 4.6 and Claude Sonnet 4.6. The issue was caused by a networking performance degradation within our cloud infrastructure that disrupted communication between components of our serving stack. We resolved the incident by migrating the affected workloads to healthy infrastructure, restoring normal service by 9:30 AM PT on March 27. https://status.claude.com/incidents/b9802k1zb5l2

The ironic thing about outages such as this one and Github's recent spate of outages are that if those vendors' sales pitches are to be believed, the vendors could just ask their LLMs to program reliable replacements overnight (okay, maybe a weekend).

It's pretty damn good, and it's seen a real exodus of conscientious users; the QuitGPT movement alone hit 1.5 million participants, with Claude skyrocketing to #1 on the App Store virtually overnight. No surprise the servers are getting hammered. time to give your devops guy his job back.
