We have seen seeing some issues over the last few weeks, several DDOS attacks, etc… which could be part of it, but based on when it happens it might be something entirely different.
Depending on where you are and what provider you use, the route you take when connecting to our systems can have a big impact on your experience. If your route takes you through a backbone provider who is having an issue, you may have increased latency, disconnections, etc… while most other players who aren’t going through the same route connect fine.
The issue we’ve had should be all clear now, but if you continue to have an issue I would start with some troubleshooting from this article. You may also visit our Technical Support forum for additional advice from various tech minded players who hang out there.
