Today’s Downtime Due to Hardware Failure, Tumblr Says

Today’s downtime was unrelated to the roll-out of its share buttons, which happened around the same time; and was not the result of a malicious attack by 4chan, as was speculated by some in the Twttrvrs and the blogosphere. ¬†“Two hardware failures in the same database cluster have dramatically lowered performance for those blogs. Recovery is moving quickly,”¬†Tumblr says.
