The mirrorlist process checks the incoming IP and queries the GeoIP.dat database (geolite from Maxmind) and then verify the actual list of valid mirrors for that country : if not enough mirrors in that country are available, the mirrorlist script adds several mirrors from a nearby country. In that specific .jp/.cn case, we can eventually select another "nearby" country and not using .cn at all, but that's something to discuss before implemeting it. Also, the current situation seems correct, can you confirm ? > > Thanks, > Mark Cheers, -- Fabian Arrotin gpg key: 56BEC54E | twitter: @arrfab
