Issues with login, signup, and ads
OpenAI status page incident write-up.
Summary
On Oct 1, 2026, between approximately 11:39 a.m. and 12:28 p.m. PDT, users experienced errors signing in to ChatGPT, creating accounts, and using the Ads Platform. A storage-capacity issue interrupted databases supporting these services. Affected services recovered by approximately 12:28 p.m. PDT.
Impact
During this period:
-
Users were temporarily unable to sign in or create accounts. Some users may also have been signed out unexpectedly.
-
The Ads Platform experienced elevated errors.
-
Some users could not complete subscription purchases.
Root Cause
A shared storage system reached its capacity limit, interrupting databases that depended on it. This caused errors in sign-in, account creation, subscription purchases, and the Ads Platform.
Resolution
Engineers freed storage capacity, adjusted database recovery settings, and restarted affected database processes. As the databases recovered, sign-in and other dependent services returned to normal. Customer-facing impact was resolved by approximately 12:28 p.m. PDT.
Prevention and Improvements
We plan to make the following change to reduce the impact of similar storage issues:
- Reduce shared storage dependencies. We plan to reduce reliance on shared storage so that capacity limits have a more contained impact on our services.
We apologize for the disruption and are continuing to strengthen the reliability of our authentication, subscription, and advertising services.
