    We observed a spike in errors affecting all Client/LoginWith[Platform] APIs. This was caused by a production deployment that was reverted.

  2. postmortem Feb 24, 2026, 10:41 PM UTC

    On February 17, 2026, between approximately 10:00 AM and 11:14 AM Pacific Time, some customers experienced increased failures when calling the Client/LoginWith\[Platform\] APIs. The issue was caused by a code regression that inadvertently removed a required validation check, leading to internal server errors. We mitigated the issue by rolling back the update. ### Impact During the impact window, customers experienced failed login attempts through the Client/LoginWith\[Platform\] APIs, with availability dropping to as low as 93%. ### Root Cause Analysis A recent code change removed a necessary null check, which caused certain requests for these APIs to fail. ### Action Items Rolled back the service update to immediately restore API availability. Deployed a hotfix to correct the code regression. Tests were also added to prevent this issue from recurring.
