GitHub Copilot: Degradation in repos contents API
Timeline of updates
- investigating
We are investigating reports of impacted performance for some GitHub services.
- resolved
On September 4, 2026, between approximately 21:45 and 22:07 UTC, some users experienced errors and elevated latency for repository operations. The incident was fully resolved at 22:23 UTC.
The cause was a capacity change that spread one of our clusters across additional availability zones; our zone-aware traffic routing kept sending requests to the original zone for performance, overloading a small set of servers while the new capacity sat idle. We resolved the incident by reverting the change and letting traffic rebalance.
We are improving per-zone capacity guarantees, cross-zone load-shedding, and pre-production testing of multi-zone changes to prevent recurrence.
Archive proof
Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert. That proves this record existed by then and has not been changed since, by anyone, Rewindex included.
