Disruption with some GitHub services

Resolved

Between 15:49 and 16:37 UTC on 20 Aug 2025, creating a new GitHub account via the web signup page consistently returned server errors, and users were unable to complete signup during this 48-minute window. We detected the issue at 16:04 UTC and restored normal signup functionality by 16:37 UTC. A recent change to signup flow logic caused all attempts to error. The change was rolled back to restore service. This exposed a gap in our test coverage that we are fixing.

Investigating

We have verified that we fixed the sign up flow and are working to ensure we don't introduce an issue like this in the future.
