When MirrorBrain is used without mod_asn, the per-file mirror lists contain places 
with missing information which looks a little silly:

List of best mirrors for IP address 83.133.126.38, located in country DE, -- (AS--
).

To avoid this, the mod_mirrorbrain Apache module, which generates the listing, 
should check whether the data is available first, and if not, leave out the empty 
placeholder.
