What happened
On September 3, 2026, ChatGPT/Codex, Claude (including Sonnet 5, Claude Code, Claude Cowork, and API), and Grok all experienced overlapping outages. ChatGPT's was a routing error lasting roughly 34 minutes; Claude's outage lasted 3 hours 6 minutes; Grok's began at 6:30am PT. Cloudflare explicitly denied being the common cause, and AWS, Google Cloud, and Azure showed no relevant issues.
Why it matters
If your product or agent pipeline depends on a single AI provider's API, a multi-hour outage like Claude's is a direct revenue and reliability hit. This simultaneous failure across three providers makes the case for implementing failover across at least two providers rather than treating any one as always-available infrastructure.
Discussion angle
What does a practical multi-provider failover setup look like for an AI agent or SaaS that currently calls one API — is the complexity worth it given how rare simultaneous outages are, or is this a black swan you accept?
