It happens that your isp may reroute the traffic to the specific server through a hop that experience issues. In that case all other services will work just fine but that one game or web service will experience issues.
The best way to identify connection issues is by running a Pinglotter and check the report after that. Please reach out to CS. They can always help to resolve any technical issues including connection ones.
