Vertex AI reliability, last 16 days

Over the last 16 days ModelBank measured 100% uptime for Vertex AI; no check failed. A further 4.3% of checks were “degraded” — the service answered, but the vendor had posted a minor incident, a single model was failing or responses were slow — and are not counted as downtime. The official status page posted no incidents in that period. The current status has held since 3d ago.

FAQ

Is Vertex AI down?

No, Vertex AI is up and working normally. ModelBank checks Google Vertex AI every 2 minutes from our global monitoring network and also reads the official status page. Last check: 44s ago.

What is Vertex AI’s uptime?

Measured by ModelBank: 100% in the last 24 hours, 100% over 30 days and 100% over 90 days.

What should I do if Vertex AI is not working?

First check this page and the official status page. If Vertex AI is up for everyone else, try clearing cache, logging out and in, switching network, or checking your API key and rate limits (HTTP 429). If it is a real outage, switch to an alternative model — see the alternatives on this page — or use a router with automatic failover.
