Claude, ChatGPT, and Grok are now operational after widespread outages on Thursday

A widespread outage has taken out popular AI platforms including ChatGPT, Claude, and Grok. — With a spike in reports on DownDetector …

Context & Ripple Effects

OpenAI has experienced several ChatGPT and API disruptions since 2023, including a January 2025 outage affecting ChatGPT and its API. Anthropic also reported elevated errors across Claude, Claude Code and API methods in March 2026.

The significance here is the overlap: confirmed errors at Anthropic and OpenAI, alongside Grok issues, interrupted several leading AI work surfaces at once rather than leaving users an obvious major-provider fallback.

First-order effects

OpenAI users can resume work in ChatGPT and Codex, while Anthropic users regain access to Claude and the affected Opus models after the reported errors.
Teams relying on Claude, ChatGPT or Grok for coding, research and other assisted workflows face an immediate continuity gap during the outage, even after services return.

Second-order effects

Simultaneous failures at OpenAI, Anthropic and Grok reduce the practical value of a simple multi-provider backup plan, because the alternatives may be unavailable at the same time.
Enterprise buyers gain a concrete reason to test manual workflows and provider failover arrangements rather than treating model availability as a given.

Third-order effects

If overlapping outages recur, reliability and outage transparency will become procurement criteria alongside model capability, favoring AI deployments designed with explicit operational fallback.
The episode points to AI assistants becoming shared work infrastructure whose concentration creates correlated operational risk across otherwise competing providers.

The trend: AI assistants are becoming critical work infrastructure, making resilience planning and correlated-service risk central to AI adoption.

during this AI outage, remember: this is how we used to write code 5 years ago

No way now ChatGPT is down too?!!! Is this the AGI takeover?

It looks like a national state brought down Claude, ChatGPT, and Grok.

Muse Spark 1.3 is the best model now since Claude, GPT and Grok all have an outage crazy

Grok, Claude and Codex all going down around the same time is... interesting to say the least

OpenAI taking everyone else offline so they can surprise launch Astra.
@levelsio @levelsio on x
If both @xAI and @claudeai are down Does that mean the Colossus GPU farm is down?
@levelsio @levelsio on x
Same It seems Claude prioritizes servers when it goes down? Another reason to run it on your VPS and not laptop
@noahrevoy @noahrevoy on x
@levelsio Claude is not working on my laptop. It is working on my server. Very odd.
@levelsio @levelsio on x
I switched my API to Claude now but now Claude also went down!
@levelsio @levelsio on x
xAI's API is down!

AI was seasonal in 2024-2025. Growth decelerated during the summer (students/people work less is the theory) and reaccelerated after Labor Day. This year, AI accelerated in July/August led by OpenAI, Grok and open-source. And today is the first time I've ever seen this:

Update: most requests are succeeding again across Claude Code, the API, and https://claude.ai/. Every model except Opus 5 and Opus 4.8 is back to baseline. Those two still have elevated errors and we're still working on it. Updates: https://status.claude.com/

An infrastructure issue is causing a partial outage across Claude Code, the API, and https://claude.ai/. We're working on it but don't have an ETA yet. We'll post here when that changes, and quickest place for updates is always https://status.claude.com/

It would be forensically useful to have a database of all the periods of downtime for AI services to figure out activity that conspicuously wound down during those moments. [embedded post]

If the economy actually became dependent on a few LLM providers, would that create a dangerous bottleneck?

I felt a great disturbance in the Force... Seriously though: Claude, ChatGPT, and Grok all went down together today. Are we blaming this on Azure East? Gemini didn't report an outage (definitely doesn't run on Azure East!), but not crazy to think they got swamped with failover tr…
