Either .co gTLDs or Go Daddy servers are blocked in China. Or, maybe .co gTLDs use a different port on DNS servers. I have no idea but I need to use VPN to access my .co websites.

Disclaimer: I didn’t jump ship from Go Daddy over the elephant or SOPA and I believe popular reactions against Go Daddy in both cases were ill-founded. Maybe you didn’t buy the backstory on the elephant and SOPA is just a matter of principle. However, they did earn my disrespect on both accounts.

This is part of my Blocked in China series.
