Like many others, we at Gotham City Drupal decided we could no longer support GoDaddy after learning of their stand on SOPA (fake-retracted though it may be). So on December 24, we moved all our DNS (20 domain names), hosting (3 servers) and numerous email and other myriad services to http://namecheap.com, which company has aggressively come out against SOPA.
We are happy to report a smooth transition was effected, with virtually no associated downtime. We are very happy with namecheap so far.
