Gravatar.com down?

If you change the linee in the plugin from:

$out = “https://www.gravatar.com/avatar.php?gravatar_id=”.md5($comment->comment_author_email);

to

$out = “https://wide.gravatar.com/avatar.php?gravatar_id=”.md5($comment->comment_author_email);

it then pulls the gravatar from a distributed cache proxy which should continue to work, even when gravatar.com goes down (so they say) plus as your using a cache of gravatars, it’s not putting as much a strain on the gravatar servers
