In June, GitHub experienced several incidents affecting service availability, with significant events occurring on June 1, 21, 28, and 29, as well as a follow-up on incidents from May 27. The June 1 incident involved delays in GitHub Actions due to excessive load on a proxy server caused by misdirected data analysis queries, which were later moved to a dedicated setup. On June 21, users with certain subscriptions faced Copilot access issues due to API authentication errors, affecting around 20% of active users, with a fix implemented promptly. The June 28 incident involved degraded availability for Codespaces, with an ongoing investigation, while June 29 saw multiple services impacted, with details to be shared in a future report. The May 27 incidents were traced back to high traffic loads on API requests, particularly the login endpoint, with responses adjusted to mitigate future occurrences. GitHub is committed to improving service reliability through enhanced testing, alerting, and procedural updates, with further insights available on their status page and engineering blog.
