In July, GitHub experienced a single incident affecting the GitHub Enterprise Importer.
July 28 Incident (21:41 UTC, lasting 5 hours 34 minutes)
Between July 28 21:41 UTC and July 29 03:15 UTC, GitHub Enterprise Importer (GEI) operated in a degraded state where migrations could not be processed.
Root Cause: A component of the GEI infrastructure had been improperly taken out of service during implementation of routine internal improvements, and it could not be restored to its previous configuration.
Resolution: This necessitated the provisioning of new resources to resolve the incident.
Preventive Measures: GitHub identified and implemented improvements around enabling the recovery of infrastructure, unit testing, and better validation using test data.
Customer Action Required: Organizations needed to add new IP ranges to applicable allow lists (20.99.172.64/28 and 135.234.59.224/28); two previous IP ranges were retired and could be removed from all lists.
