What happened
On Monday Aug 31, 2026, both OpenAI's ChatGPT Work and Microsoft's Exchange Online (Outlook) experienced simultaneous but reportedly unconnected outages. ChatGPT Work showed elevated errors and latency for roughly three hours, with users across multiple subscription plans unable to start or continue tasks; Downdetector peaked at ~1,100 reports for OpenAI and ~4,600 for Outlook.
Why it matters
If your team or product depends on ChatGPT Work as an enterprise AI agent runtime, this outage is a concrete reminder to have fallback workflows or alternative model endpoints configured rather than treating any single vendor's status page as guaranteed uptime.
Discussion angle
How much operational risk are you carrying by routing production agent tasks through a single provider like ChatGPT Work, and what does a realistic fallback look like when that provider is down for hours?
