Railway - We're investigating routing failures for deployments using static IPs for egress. – Incident details

An update to our routing control plane incorrectly propagated a bad route for regional egress proxies, this led to the drop of static IP egress traffic from 21:28 UTC to approximately 22:00 UTC. Our static IP monitoring was configured globally in our largest region. We're adding regional static IP monitoring to catch this in staged rollouts (aka, much quicker).

We've reverted the routing config and static IPs traffic is flowing normally.

we've identified a configuration change in our network routing config that looks to have caused the problem. We're rolling out a fix globally.
