How to Accept DNS Propagation After Server Migration with Speed Tests
Keywords: migration speed test,DNS propagation,server migration
Category: Use Cases
Tool: SpeedCE | English UI
The classic post-migration trap: you changed DNS, but some provinces still resolve the old IP. Use SpeedCE HTTPS on the domain (not the IP), China nodes, every 10 minutes, and watch failed nodes shrink.
Still red nationwide → new server web/cert/firewall issue; scattered red decreasing → DNS cache, wait for TTL; one province stays red → regional DNS problem.
Lower TTL before migration; use the map for acceptance. https://www.speedce.com
