Railway - Cert discrepancy between Fastly and Railway leading to SAN errors. The network team is actively triaging the issue for affected customers. – Incident details

Network behavior is back to nominal.

Manual workarounds for customers show that access is restored, we are working with our upstream vendor to implement domain forwarding to mitigate customer misconfiguration.

For some affected domains, cert provisioning is inoperable, this is due to incorrect domain configuration, please re-add your domains to triage the issue.
