I have no direct experience with live UPS lookups but I make a point to 
not rely on external servers for images, counters or anything else. In 
my experience the use of remote servers can slow and/or break things. I 
prefer to keep all functions local and I use internal UPS lookups. It is 
a tad more work but I feel more comfortable.
