GitHub Outage Hits 12,000 Organizations

GitHub experienced a major outage on October 7, 2026, affecting more than 12,000 organizations with failed requests. The incident stemmed from a new regression in automated maintenance that routed write requests to non-existent database servers. While 5.6% of requests failed initially, a second outage occurred at 16:52 UTC when a misbehaving machine was incorrectly elected leader again.
