I noticed this as just after seeing your email.

> Did I miss an email about their domain change?

> Anyways, I think all is good now.

Very good.  In the future, if you run into a problem feeding from Purdue, you
can use idd.unidata.ucar.edu as a failover.  Please stick with Purdue when
they are up, however.
