The timestamp inconsistency teraflop points out is
interesting — but the bigger takeaway for me is that
Railway's own automated API health checks caught the
failure at 22:10, a full 10 minutes before the root
cause was identified.
That's external dependency monitoring working exactly
as it should. Most teams only monitor their own
infrastructure. When a cloud provider, payment gateway,
or third-party API fails — your own dashboards show
green while users see failures.
The lesson isn't specific to GCP — it's that monitoring
what you depend on but don't control is just as
important as monitoring what you own.
