Platform Wide Rolling Host Reboots

Final update

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 95% of the fleet has been restarted. The remaining hosts are expected to be restarted over the next 30m. 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 to by the team. We will continue to provide updates on progress as the rollout continues.

   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.

    Rolling host restarts are beginning in all regions. Machines, volumes, and MPG instances will be unavailable for approximately 15-20 minutes when their hosts are restarted during this process. Users should expect a period of disruption or downtime for their apps during this, especially if they are running on a single machine. We will provide further updates as the rollout progresses.
