Run the Dota 2 ping test to compare US East, US West, Europe West, South America, Southeast Asia, Japan, Australia, and India. Every testable mapping is `regional`; Dubai is unsupported without a matching probe.
Use PartyPing to compare network directions, but use the region ping shown by Dota 2 for the final queue choice. In a party, compare the same candidates for every member instead of optimizing only for the host.
Valve's Steam Datagram Relay can carry game traffic through relay infrastructure and select routes dynamically. A browser probe does not follow that same path, so the numbers need not match. What matters is whether their direction changes consistently in the same time window.
Retest a fixed region and record P10–P90, missing replies, and in-match data when fights feel delayed. If every direction worsens, inspect the local network first. If only the Dota 2 client changes, check Steam/Dota service and relay routing.
