Tim,
 
It's a good question, and at least right now, I can say the answer is no.  Normally, when iChain sees that one of the backend servers is down, it will not try to use it for anything.  However, with all the weird stuff that was going on since yesterday, we started wondering the same thing that you did, so we manually removed the broken server out of the iChain configuration. 
 
I see two possibilities here.  One is that we installed two new extensions yesterday and one of them is causing problems.  The other, and probably most likely, is that this has always happened and it is only noticeable when trying to do an import.  Any other ideas, anyone?
