Outage in Fly.io
High number of 5XX on the Machines API and dashboard
Resolved MajorIncident Report
Summary AI Generated
Fly.io's Machines API and Dashboard experienced a 10-hour major outage caused by a failure in an internal authentication service. While existing machines and apps continued running normally, users were unable to interact with the API or Dashboard, and some Managed Postgres v1 clusters became degraded as a secondary impact. The incident was resolved after a fix was implemented and monitored, with full resolution confirmed later that day.
Existing machines are unaffected. We are investigating the issue.
