The Vercel outage of September 27, 2026, as measured from 10 regions

Region-by-region timeline

When each monitored region started failing and when it recovered, per RealUptime's own probes. A region not listed here never failed during this incident.

How this was measured

This record comes only from RealUptime's own scheduled probes against Vercel's public, unauthenticated endpoints, run from 10 named regions. It is never built from user reports or from Vercel's own status page, and it does not change once this incident closes: this page is the permanent record, not a live view.
