So I’m just about to write a post about how gravatar.com was down for ages and now seems to be back. But, their site is current giving me a 503 error. Super. Gravatar was great for a bit but then became incredibly slow, obviously because of the increased popularity, then just stopped working completely for a while. Looks like they aren’t out of the woods yet. They should go talk to Matt and co. over at Automattic.
