Azure latency check — browser-measured RTT to Microsoft Azure regions using Cognitive Services regional endpoints.Measured live from your browser to 0 Azure region endpoints. Three samples per region in parallel, fetch(no-cors) + median ms reported, four-second timeout.

// endpoint used
<region>.api.cognitive.microsoft.com — Cognitive Services regional subdomains. Unauth requests return fast, while TLS termination happens at the region's edge.
// what it measures
Per region: 4 sequential samples, first discarded as TLS warm-up, median of the remaining 3 reported. Numbers approximate TCP + TLS + first-byte time. Relative ordering between regions is accurate.
// what it doesn't
We don't persist runs, send your IP anywhere, or compare inter-region paths. For serious benchmarking, mtr beats browser fetch timing every time.
