Downdetector reports started spiking over an hour ago but there still isn't a single status that isn't a green checkmark on the status page.
E.g. it was mostly us-central1 region affected, and in there only some services (e.g. regular instances, and GKE kubernetes were not affected in any region). So if we ask "what the percentage of GCP is down", it might well be it's less than the threshold.
On the other hand, about a month ago, 2025-05-19 there was an 8-hour long incident with Spot VM instances affecting 5 regions, and which was way more important to our company, but it didn't make any headlines.
then such pages should report a partial failure. Indeed the GCP outage page lists an orange "One or more regions affected" marker, but all services show the green "Available" marker, which apparently is not true.
The issue is that they don't want to. (For claiming good uptime, which may even be true for average user, if most outages affect only small groups)
