i don’t know about whatever policies you may have about download sites ie mirrors but what about mega.co.nz ?.
you get 50 GB free and it is fast (i download stuff from there all the time) and it is secure because as far as i know no one can modify or upload without the username and password but can download without it just by posting a link.
I am not one hundred percent sure but I think we have a statistic plugin active to actually count the downloads of every release. This is not possible with the mega.co.nz
