|---|---|
| Region code | europe-west6 |
| Region name | Zurich |
| Datacentre city | Zurich, Switzerland, CH |
| Coordinates | 47.38, 8.54 |
| Published IPv4 prefixes | 10 |
| Probe endpoint | https://storage.europe-west6.rep.googleapis.com/ |
| Probe style | timed blind — the endpoint sends no CORS headers |
| Verification | Probed 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.
Light in fibre covers about 100 km per millisecond of round trip. These are the great-circle distances to Zurich, Switzerland and the latency no network can beat — not a measurement, a limit. What you actually measure is this plus routing.

Within 75 km of Zurich, Switzerland — 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.
These figures are geometry. Your own round trip to europe-west6 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.
