In case anyone was wondering (and happens to read this)

From http://status.livejournal.org/

We can now publicly disclose that we have been experiencing a large-scale DDoS attack the last two days, which has been the reason for the site issues most users have been experiencing. The traffic load has been immense, at many times our normal load level, and the attack is still on-going. We are in constant contact with our providers to mitigate the attack as best as possible. We again apologize for the disruption to LiveJournal usage, and are working to get everything back to normal as soon as we can. Thank you!

ETA: My LJ flist works fine, I just can't post anything. Not even comments. :(
