Can't get to freenode

[Xbehave]

I can't get on irc.freenode.net (or irc.ubuntu.com) in konversation or the java applet, any ideas why?
Can i find out if i've been banned? I was connecting a lot the other day but i doubt it was enough to be flagged as a dos
Or if my uncles IP has been banned for malware? (stupid sky router seams infected tbh but i dunno how to check)
Or if freenode itself is down? this seams unlikely as i get a response

OH NO !!

You aren't banned, if you were, chanserv/etc would tell you you were banned when joining the channel where you were banned.
Are you using a proxy where you are now? I don't think freenode allows proxy's, so look into that.

How can i find out if im behind a proxy?
