If there are ever problems accessing motherlode, please let us know
immediately.  I only know of a couple of times that it was unaccessible
recently, so this is surprising.  Were the bundles pointing to the
latest dataset or a specific one that may have been scoured off?

We have thought about this, but currently do not have the capability
to query servers.  That was an eventual goal of the THREDDS project.

I agree that would be a good feature.  

However, you can change the data source when you load in the bundle.
When you select Open... for the bundle, you can click the "Change data"
button on the Open dialog and it will prompt you for the new datasource.
You can then select a new source for the data.  Not automatic, but it
is a way around the problem if the server is down.
