Map the entire request
List visitor regions and access networks, then locate your database, payment endpoints, object storage and external APIs. A nearby web server can still be slow when every request waits for a distant database.
Compare under matching conditions
Measure TCP connection, TLS handshake, time to first byte and complete request duration during busy and quiet periods. Keep the client, payload and target operation consistent. Save multiple samples with timestamps. ICMP latency does not replace an application test.
Place recovery separately
Choose the primary application region first, then plan static delivery and off-site backups. Cross-region database replication introduces bandwidth and consistency decisions. Several instances are not automatically highly available: health checks and failover must be exercised.
Keep the decision reproducible
Save the region, access network, destination, time window and ordered configuration with your results. Available POWOKE locations come from the current catalog. Explain which audience a region serves instead of declaring an unconditional fastest location.
