When multiple values exist for a zone pair, P50 (median) is used.

Methodology
P50 median RTTCloud63 RTT = A→B + B→A
Azure Docs: values are sourced from
Azure Network Latency
where Microsoft measures inter-region round-trip latency using internal backbone probes sampled every minute,
then publishes monthly P50 (median) RTT values over a rolling 30-day window. Microsoft notes that updates are
periodic (typically every 6 to 9 months) and not all public regions are listed until data is available.
Cloud63: measurements are one-way, so we compute P50 per direction, then derive RTT by summing
P50(A→B) + P50(B→A). If one direction is missing, latency is shown as unknown.
