Gravatars will be OK!
As you may have noticed, gravatar.com has been down for a few days, but have no fear. I had an email from Tom Werner this morning which explains everything:
I left for vacation to China on the 11th, and it seems I forgot to renew the gravatar.com domain before I left. Now I have the rude awakening here in Hangzhou that gravatars have been down since the 15th. Curse my timing! I am renewing the domain right now but it might take a little while to go through and there might be other problems I don’t forsee. Could you to make a little note on your weblog informing the peoples of this misfortune? Tell them I still care!!!!
Try and enjoy your holiday Tom!
