OpenAI investigating elevated latency across ChatGPT and API
OpenAI confirmed on May 27, 2026 that it is investigating elevated latency issues affecting ChatGPT and its API. The company announced the investigation at approximately 8:15 AM PT.
Issue scope
According to OpenAI's system status page, the latency issues are affecting:
- ChatGPT web interface
- OpenAI API endpoints
A separate issue impacting FEDRamp users (government cloud customers) is also being monitored, though OpenAI states a fix has been applied to that specific problem.
Company response
OpenAI's team posted updates to its status page indicating they are "investigating elevated latencies across the board for API and ChatGPT." No timeline for resolution has been provided.
The latency issues represent degraded performance rather than a complete outage. Users can still access ChatGPT and the API, but response times are slower than normal.
What this means
Latency spikes on OpenAI's infrastructure affect millions of users and thousands of applications built on its API. For enterprises running production systems on ChatGPT's API, elevated latency can cascade into customer-facing performance issues. The fact that OpenAI publicly acknowledged the issue within hours suggests significant impact across its user base. FEDRamp certification enables government use of AI services, making that segment particularly sensitive to downtime or performance degradation.
