Server is returning error 500 when users try to publish packages and the selected server is at us-west region

After monitoring the registry, we observed no further issues. It is important to note that, because some packages were rebuilt, users will need to clear their cached fingerprints, as those packages now have new checksums. We will publish a detailed RCA next week with more information about the incident and its root cause.

During a past incident, some packages were rebuilt causing their hashes/checksum to change. Those packages will fail when installing, to fix this issue, users must remove the fingerprints of those packages. The fingerprints are stored at ~/.swiftpm/security/fingerprints/<scope>.<name>.json.
