I have ties to Andreas of CPAN b/c of my mod_perl involvement and can
ask if someone wants me to.
The largest reason for where something show up though is if you just
release the module or if you've 'registered' the namespace. There is
also permissions at plan 'MAINT/CO-MAINT' in PAUSE terms.
mod_perl being CO-MAINT for APML but never once released by it.
Also some CPAN urls result in redirects, others do not. Its quite a
subtantial load difference for them to have to process 5 redirects per
request from fbd ports vs none.
