This demonstrates yet again why global configurations, global services, and global anycast VIP routing should be considered an anti pattern. gcp should be designed in a way where the term “global outage” isn’t a word in their vocabulary.
And why enterprises clamoring for AWS to feature match Google's global stuff (theoretically making I.T. easier) instead of remaining regionally isolated (making I.T. actually more resilient, without extra work if I.T. operators can figure out infra-as-code patterns) should STFU and learn themselves some Terraform, Pulumi, or etc.
Also, AWS, if you're in this thread, stop with the recent cross-region coupling features already. Google's doing it wrong, explain that, and be patient, the market share will come back to you when they run out of the GCP subsidy dollars.
