"As many of you know, LiveJournal was the victim of a DDoS attack yesterday, resulting in several hours of downtime.
"We appreciate your patience as we work on resolving the remaining issues resulting from yesterday's attack."
A user of Livejournal myself, its enforced downtime did leave me somewhat perplexed. I am personally glad to see that it has recovered from its ordeal.
