Tom Werner just wrote about it: the distribute gravatar proxy system is ready (read more about it here). This way the main gravatar server will be relieved a little bit and even if there’s a problem with the mainserver the gravatars will still show up just fine.

All you need to do is edit the gravatars plugin (change the url to wide.gravatar.com* where * is the query string which doesn’t need to be edited) :tup:
