Amprolla does not rely on any of this, since it uses debian repos and
pkgmaster, directly, without any 302, and then it produced the merged
repos that are successively rsynced to pkgmaster.

Unfortunatly, we can't check also all the debian mirrors. I mean, we
physically cannot do that, since those are normally behind a CDN, and
you only reach the one that is closer to the server that does the
check, and there is no guarantee that you hit the same one that a
mirror hits and/or that you hit the same one that a client hits...

There is literally no way out of it.

The main checking script has always been at:
