Although we completed the network maintenance, the site remained unavailable or slow for many users until Wednesday night. Unfortunately, we discovered many underlying issues with our network installation, and decided to take additional downtime to fix everything up.
There should be no site-wide network/reachability issues following this announcement. Although you might not notice any major differences, this upgrade is certainly a very good thing for us, and will let us handle increased traffic at faster speeds.
The LiveJournal team and I thank you deeply for your patience, and are working hard to keep everyone informed better before we make changes or experience unexpected problems.
Andreas - LJ Ops.
