QuoteWe are aware of issues on the public internet that are causing connection problems for some players. Specifically, players are affected whose connection takes a certain path through the internet to reach our servers. We have passed the problem on to the appropriate organizations. Unfortunately, however, we have to say that these are often lengthy processes, and we cannot speed them up. We are already evaluating possible approaches to work around the problem, at least for our users. However, neither you nor we can solve the underlying problem.
