Los chicos de Gravatar están sin servir sus (gr)avatares.
Gravatar.com Admin is Down for Maintenance
Signup and login are disabled while Gravatar 2.0 is being phased in. Extreme load has forced me to do this earlier than anticipated, so please be patient during this period. It may be several weeks before signup/login is re-enabled. I apologize for the inconvenience, but I really need to get gravatar serving responsive again. In the meantime, please keep up with site events at the Gravatar Weblog.
Además, el Gravatar Weblog está caído y dolirido. Esperemos que se recupere pronto.
