Last week SourceForge, which we use for hosting, was having connectivity issues. This caused the Irrlicht homepage and forum to work badly. Over the last days most things started working again – except the forum continues to be broken. Old posts can be read but everything else is currently not working. We try to figure out what is going on. In the meantime if you have urgent questions you can discuss them on IRC (server: irc.freenode.net channel: #irrlicht).
