I can't seem to be able to access your site at the moment but in the past few weeks, we've received reports of similar issues from other folks hosted with GoDaddy on a Windows server. We're not able to connect to such sites from WordPress.com servers anymore.
GoDaddy recommends that you switch to a Linux server instead:

Do not hesitate to contact them about this issue, they're aware of the problem and have helped other users switch in the past few weeks.
