Both DSJ and Calabash are hosted sites through Savant Media in STJ so basically when you try to go to either of those sites you are really going to the same place (site).
I think there is probably an issue with the DNS servers you use or a routing issue.
I'd be happy to troubleshoot this with you if you want.
Give me a PM.

Aha - Bill has dug deeper. I am pretty sure Savant uses a stateside host somewhere, so it could be that their box is down or they have connectivity/network issues.
