I think there's a lot of misunderstanding going on because of the way that 
has set up our CDN.

It is true that right now, pkg.f.o returns SRV records for all known mirrors.

It is also true that previously mentioned pkg.eu.f.o returns the one and only 
SRV record
for the one mirror in Europe.

However, I am planning for a day when our CDN is administered in a more 
fashion. That is...

I envisage pkg.f.o not returning all known mirrors (because there will be too 
many as
the CDN grows), but instead pkg.f.o would return only the 3 closest mirrors.

Meanwhile, pkg.eu.f.o would grow to return records for the top-3 closest 
servers in Europe.

Just because the amount of machines that we have available for our CDN is 
small, doesn't
mean that it will be small forever.

Eventually (as is the plan), the list of servers should far exceed the number 
of SRV records
you will want to return. And when we get to that point, I highly recommend that 
we allow the
user to choose the CDN specific to their country (at the very least).
