For more clarification: Trouble connecting to either region does not guarantee a problem on any server, and is likely an issue on the route itself. In both cases, your ISP is responsible for part of the route, and then they contract a peering partner to complete the connection path. The peering partner in the US is likely a different company than the one connecting over to the EU. The ISP nodes used in both directions will be different, as well.
