I'm on their mailing list and just received an email from them saying...
Hello,
In the past week there has been some issues with our email/server. It seemed to fix itself but then got buggy again. All last night we tried to figure it out end ended up moving servers. While our DNS cache propagates we are still hitting the old server which is why our site has not been loading since a little before 5am.
Usually this takes about 24 hours.....
Sorry for any inconvenience this may have caused....
For the time being you can contact us at this email

Normally I wouldn't post the content of an email but in this case I'm sure they would want people to have the info.
