Resolved after 1 hour 14 minutes, affecting Europe / Frankfurt and Europe / Frankfurt and 1 more, on November 11, 2025.

postmortem Nov 13, 2025, 12:21 PM UTC

Customers experienced intermittent service issues with core operations, including deployments and authentication, between 2:58 and 10:40 UTC. The disruption was caused by a core system component reaching its maximum connection limit. Our engineering team successfully identified the issue, implemented a configuration update to increase connection capacity, and fully restored service by 10:40 UTC. We are also conducting a full analysis to understand the unexpected usage increase and are enhancing our monitoring for earlier detection of similar events in the future. We apologize for the inconvenience this may have caused.
