Platform Wide Rolling Host Reboots

1. 16:22 UTC Fly.io status page · Reported Platform Wide Rolling Host Reboots
2. 21:11 UTC Fly.io status page · Identified Host restarts are continuing in phases across all regions - at this point, roughly 65% of all hosts across the fleet have been restarted. Only a subset of hosts in each region will be down at each time. We expect this process to take multiple hours to complete in full, with larger regions taking the longest to complete. In general, Fly Machines should return to whatever state they were in prior to the host reboot, unless the Machine's restart policy says otherwise. Rollout phases were scheduled to minimize impact to Managed Postgres Clusters within those regions; however, MPG users will…
3. 21:41 UTC Fly.io status page · Identified Host restarts are continuing in phases across all regions - at this point, roughly 70% of all hosts across the fleet have been restarted. Only a subset of hosts in each region will be down at each time. We expect this process to take multiple hours to complete in full, with larger regions taking the longest to complete.

6. 00:05 UTC Fly.io status page · Identified Host restarts are continuing in phases across all regions - at this point, roughly 90% of all hosts across the fleet have been restarted. Only a subset of hosts in each region will be down at each time. We expect this process to take multiple hours to complete in full, with larger regions taking the longest to complete. In general, Fly Machines should return to whatever state they were in prior to the host reboot, unless the Machine's restart policy says otherwise.

7. 00:45 UTC Fly.io status page · Identified As a mitigation measure for PwnEscape (Linux Kernel CVE-2026-99999), host restarts are continuing in phases across all regions. At this point, more than 90% of the fleet has been restarted. The remaining hosts are expected to be restarted over the next 2h30m. Only a subset of hosts in each region will be down at each time. In general, Fly Machines should return to whatever state they were in prior to the host reboot, unless the Machine's restart policy says otherwise. MPG users will likely see elevated primary standby switchovers during this period. Impacted MPG clusters are being attended…
