- Remove depricated cdn.debian.net and http.debian.net
- Add http://deb.debian.org
Please revise the list while at it,
While not enforced in any we perhaps we can consider something something like a 4+4+2(+1) (https/http/ftp/(master if available) and CDN first) to avoid having unnecessary long lists of mirrors? I think you can safely assume at if you cannot connect to 10+ sites worldwide you have connectivity issues rather than flakey mirrors.
Something like this perhaps? I prioritized mirrors that are carries everything (ALL) and tried use ones with good overall connectivity and coverage. Many mirrors seems to have discontinued their ftp service.
