Thanks for all this...  I now mostly understand what was going on.

The *intent* of the nginx setup was do to the following, via 3 server blocks:

	* ip address - redirects to example.com
	* example.com - goes to appserver 1
	* failover domains - goes to appserver 2 (which requires the Host header)

I naively expected this sort of request to be processed by the first block, not the last.  

Looking at the docs, it seems I just need to do an empty host block now.
