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