I’m also on a EU server, but it seems to work now.
Before, I couldn’t even access my account on guildwars2.com. When I tried to reset my password, I got this message: 502 – “Web server received an invalid response while acting as a gateway or proxy server.
There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.”
Obviously I was also able to log in now, just wanted to mention it.
