Yeah that feed tends to come and go.  It usually comes back after a while - a lot of people use those feeds, especially for currency conversion, so they typically don't stay down for long.  Last year they ran out of disk space, and it took a few days for it to come back.

I'll keep an eye on it and if it doesn't come back, I'll see if I can locate an alternative provider.

Chumby used to use a commercial provider that was more reliable, but it was *way* too expensive to use now.
