(LiveJournal News) The long-awaited server move takes place this Tuesday, November 18, at 8:00 a.m. PST. We’re moving the site from servers based in San Francisco to the servers in our new data center in Montana. A massive data move like this takes a lot of heavy lifting, and to haul all that data from San Francisco to Montana, we have to take the site down, starting at 8:00 a.m. PST on Tuesday morning. [...]
During the downtime, nothing on LJ will be available—no posting, no Friends page, no LJ mail, nada. When we bring the site back up, we’re going to ease into it rather than open up a floodgate of traffic. Posting might not be immediately available or the site could be slow to load for a while.
LiveJournal expects the migration to last approximately four hours, although it may take longer for most of their services to come back online.
It will be interesting to see whether this move improves LiveJournal outside of Russia (where it is extremly popular) in the face of international competiton from platform hosted services like Blogger, WordPress and TypePad (owned by Six Apart).
