GitHub: Disruption with some GitHub services
Timeline of updates
- resolved
On September 23, 2025, between 15:29 UTC and 17:38 UTC and also on September 24, 2025 between 14:02 UTC and 15:12 UTC, email deliveries were delayed up to 50 minutes which resulted in significant delays for most types of email notifications. This occurred due to an unusually high volume of traffic which caused resource contention on some of our outbound email servers. We have updated the configuration we use to better allocate capacity when there is a high volume of traffic and are also updating our monitors so we can detect this type of issue before it becomes a customer impacting incident.
From GitHub’s published incident history: for incidents before Rewindex began polling this status page, only the final update text is available.
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.

This incident predates live tracking (October 17, 2026). It came from the vendor’s own published history, which is not covered by checkpoints.
