Mirrors are volunteers who give up a part of their bandwidth as a service to the TeX community, essentially enrolling in an ongoing cash contribution to people that they will never meet.  Some mirrors can spare less bandwidth than others, or share more during nighttime hours, etc.  (There is a monitoring system of mirrors to see that they are functional but it is imprudent to be aggressively demanding.)

Just as speculation, there are different definitions of `M'.  (It is also the case that mirrors update their holdings nightly so any change would reach some mirrors at different times than others; that sometimes accounts for a difference.)

The TUG page is right.  The URL starting with "mirror.ctan.org" goes to a program that sends people who want something to a mirror picked at random from their country.  Had you clicked it again then you likely would have gotten a different mirror. This shares the load among the people who have been good enough to volunteer for what is frankly not a glamorous project.

`Not always,' said Stephen.
