Because the list of checksums was not from that server, I would think.
But maybe my analysis based on output from users is wrong. Please prove me
wrong and tell me how to fix it.

If that is happening, sure. Proof it to me. Everybody is complaining, but
nobody is debugging and analysing. Apt and smart does not have this
problem using the same metadata (but no mirrors).

In fact, if you only use apt.sw.be, there is NO problem.

But they do track their mirrors and modify the mirrorlist accordingly.

If you come up with the cause, I can fix the problem. What I gave you was
my theory.
