Measurement notes

Why are outbound and inbound values different?

Outbound probes start at London; inbound probes start at the remote PoP. Each value is a complete round trip. Routing, congestion and the measurement origin can produce different results in the two directions.

What do the probe statistics describe?

Minimum, maximum and standard deviation describe the published samples in each route's probe round. Each route includes its sample count, interval and timestamp. A short round does not establish long-term reliability or an SLA.

What is measured, and what is modeled?

The comparison table shows measured RTT. Fiber floors, efficiency, jitter estimates and trend comparisons on the individual route pages are calculated indicators. They do not identify a physical cable path or replace loss and jitter measurements. Read the methodology.
