Then, can we have the ERROR message, please?
Otherwise the only explanation I can guess is that a mirror grabs the 
contents of a repository exactly in the second the repository is updated 
and that is unlikely, particularly if more than one mirror is involved.

We do care, but the mirrors seem to be fine and hence we cannot debug 
what you have seen before.
