Conan Exiles is instituting a new ping block on official servers
Officially, the reason behind the region blocking in Conan Exiles is to make sure that players are always on a server that can support similar ping rates and fair gameplay. Whether or not you believe that idea is immaterial; people have gotten around the region block regardless, and so another layer of blocking is being put into place with the new MaxPingAllowed system on the game’s official servers.
Players with a ping rate over 140 will not be allowed on the servers with a maximum ping set, so players outside of the appropriate region (or those with particularly bad connections) will now be automatically blocked by the server. Some official servers will still have no ping maximum, so players can still play without region blocks if they want, but the majority will be limited to servers with a low ping rate and other players with similarly low ping.
