Hi all, Now I added BGP Autonomous System Number (ASNum) based debian mirror function to cdn.debian.net. When DNS query is come from ASNum which listed at http://debiancdn.appspot.com/managesurrogate, cdn.debian.net returns same ASNum's mirror IP address. When no mirror locates in same ASN, cdn.d.n return mirror server (up to four servers) from country, continent, or North America mirrors. Thanks. -- ARAKI Yasuhiro
