Same for me, and it has always been the case since I came here. But it is almost never down for a whole day though. Sometimes (many times actually !!) it works, but badly : heavy topics don't show properly, and I have to reload them several times. The trick is to click "reply" so as to read what is missing (because the rest shows up then).
Weirdly, I have never experienced anything like this when I was working on a network machine with Netscape...
