Update: It took a bit longer to get the wiki and other smaller bits working again, and some things may continue to be wonky. Expect these to be fixed over the next couple days.
there was a brief outage today due to a server configuration mishap.
I intended to reconfigure the webserver so that http://faforever.com and https://faforever.com works properly and shows our main website. This worked great. However, for an as yet unknown reason, this led to HTTPS being forced on for all of our subdomains including forums.faforever.com and content.faforever.com, which broke the forums and almost all client functionality.
I quickly fixed this and everything should be back to normal now.
Please report any issues on the forum or to a moderator on irc.
