What happened to SourceForge?

I was going to download elementary OS beta 2, but SF.net showed me the message: The sourceforge.net website is temporarily in static offline mode. Only a very limited set of project pages are available until the main website returns to service. This message appears after search or clicking any links from the frontpage. For a second I notice hitting URL http://sourceforge.net/#!/Testing then redirect to sourceforge.net/error-404.html. I'd be grateful if anybody could provide me with more information, thanks!
