For those who still can't access LJ
From the status page:
LiveJournal has been under a DDoS attack since Thursday, August 6th. A DDoS attack is focused heavy traffic in an attempt to make the site unavailable; not an attempt to gain access to anyone's account or personal information. We have taken steps to filter this traffic so that the site can remain accessible.
The site is running normally for most users at this time. Because of the mitigation procedures required to keep the site up and running, however, some users may not be able to access the site or post entries or comments from some locations and browsers. This is not account-specific, and you may be able to access the site from a different computer or network.
Our Operations staff will continue to monitor the situation and take appropriate actions in order to ensure the continued health of the site. Additional updates will be posted in lj_maintenance
LiveJournal may be unreachable, or intermittently slow to load. Users may also receive error messages when trying to access the site or when posting new entries or comments. This is due to an ongoing, coordinated attack on the site. More information is available here. We are working around this attack as quickly as we can, and we apologize for the inconvenience.
The link goes to the lj_maintenance post explaining about the DDoS attack, and in the comments to that post some people who can't otherwise access LJ report being able to do so via a proxy.
