6 september 2026ChatGPT, Claude and Grok down at once: your failover plan
On 3 September 2026, ChatGPT, Claude and Grok all suffered outages on the same afternoon, each from an independent cause: a routing error at OpenAI, an infrastructure issue at Anthropic and a compute-centre failure behind Grok. A runtime failover plan for Azure teams: Foundry's model router with automatic fallback, APIM's AI gateway and circuit breaker, what redundancy really costs, and the Data Zone and DORA constraints that shape it.
