Round-trip time from your browser to every Akamai Cloud (Linode) region — 24 of them, 8 in Europe, 7 in Asia, 7 in North America, 1 in Oceania, 1 in South America — and how much of each is distance rather than the network.
Object-storage endpoints answer per datacentre, timed blind — no CORS headers.
The first request of a sweep is discarded — it pays for DNS, TCP and TLS — so every sample after it is essentially one round trip, and the reported figure is the fastest of them.

Prefix counts come from Linode’s own published feed. Each region links to its distance, its physical floor and the endpoint used to time it.
Open the instrument, select Linode, choose regions and run a sweep. Nothing is pre-selected and nothing runs until you press the button.
