Error: failed to fetch an image or build from source: error rendering push status stream: blob upload unknown

Sorry for the inconvenience. We have a “backup” registry that only keeps storage in the IAD region, which we think will work around the issue you are seeing. Try it out with:

% FLY_REGISTRY_HOST=registry-iad.fly.io fly deploy

Use this if you are doing docker push directly to the registry:

% FLY_REGISTRY_HOST=registry-iad.fly.io fly auth docker
% docker push registry-iad.fly.io/your-app:latest

We are working to fix the core issue. We’ll report back once that’s done. In the meantime, we hope the above unblocks deployments.
