GCP europe-west9 latency

Paris. How long a round trip from your machine to this region takes — and how much of that distance alone demands.

Region codeeurope-west9
Region nameParis
Datacentre cityParis, France, FR
Coordinates48.86, 2.35
Published IPv4 prefixes7
Probe endpointhttps://storage.europe-west9.rep.googleapis.com/
Probe styletimed blind — the endpoint sends no CORS headers
VerificationProbed on this region’s dedicated regional storage endpoint — one address per region, no wildcard DNS — with identity confirmed by a single gcping call per sweep. The recorded range-check predates this endpoint and covered an earlier host. Checked 2026-08-21.

Coordinates are the real datacentre city rather than the marketing region name, because they feed the distance maths below.

Distance, and the floor it sets

Light in fibre covers about 100 km per millisecond of round trip. These are the great-circle distances to Paris, France and the latency no network can beat — not a measurement, a limit. What you actually measure is this plus routing.

Other regions in this metro

Within 75 km of Paris, France — near enough that distance sets no meaningful floor between them. When several sit in one city, the fastest is the city’s real floor; a slower neighbour is usually the endpoint’s own server time.

Measure it yourself

These figures are geometry. Your own round trip to europe-west9 depends on your connection and the route it takes — open the instrument, pick GCP, and sweep. Every region is timed from your browser against the endpoint listed above, and the result is split into the part physics demands and the part the network added.
