From what I've read in other comments, the root cause seems to have been automatic account suspension as an anti-abuse measures.

It's also telling that Railway describes the root cause simply as "Google Cloud Platform has suspended Railway's production account." It then mentions this

> At 22:20 UTC on May 19, Google Cloud placed Railway’s production account into a suspended status incorrectly, as part of an automated action. This action extended to many accounts within Google Cloud. As this was a platform-wide action, there was no proactive outreach to individual customers prior to the restriction.

The why is conspicuously absent, but this sort of sweep is indeed consistent with anti-abuse measure.

If this is the case I would be cautious in accusing a cloud provider of wrongdoing. Many things need to go awfully wrong to trigger this sort of alarm, and I'm not talking about GCP's anti-abuse system. In fact, it's telling that no reputable, well established business is reporting any impact. The whole point of any anti-abuse system is to suspend accounts that are caught engaging in some sort of abuse.
