Image pull times in IAD have returned to normal.

We have implemented a fix and are monitoring results.

We have identified the cause of the issue and are working on a fix.

We are investigating slow image pulls within Fly Machines in IAD. Newly created or updated Machines are taking longer to start, which may cause deployments to time out. Machines start successfully after the delay. Consider creating Machines in alternate regions, if possible, or running `fly deploy --wait-timeout 10m` to give Machines up to 10 minutes to prepare images and start.
