Outage in Expo
EAS Outage
Resolved MajorIncident Report
Summary AI Generated
A networking outage at Expo's macOS data center caused EAS Build and EAS Submit services to become unavailable for 7.2 hours. The outage was caused by the data center provider's network issues, which they worked to resolve with their upstream providers. Service was restored after the data center's network partially recovered, with job processing capacity temporarily doubled to clear the backlog of affected build and submission jobs.
There is a networking outage in our macOS data center. We are waiting for a fix on their end.

The data center’s network has partially recovered and the availability of the affected services (iOS build and submission jobs and macOS CI jobs) is back.
We are monitoring service health. The backlog of affected jobs is being processed as fast as possible - specifically, compared to before this incident about twice as many jobs are running. Thank you for your patience and understanding.

Our data center provider is still working on the issue. We noticed one of our racks became reachable again and started processing jobs successfully but that rack is now offline again. We are monitoring the servers’ network and status updates from the data center and are ready to work on restoring availability of iOS build jobs and macOS workflows when we get confirmation the data center is healthy again. Thank you for your understanding.
