Hi

You receive this mail because you are listed as contact for:
  debian.uvigo.es

Please select a upstream mirror different to ftp.de.debian.org, for
example the system behind it: debian.inf.tu-dresden.de.  Only http is
guaranteed to be available at ftp.<CC>.d.o sites.

Please update your ftpsync version.  Running a current ftpsync version
makes sure the update is done in a way apt does not blow up.  Also it
allows us to monitor the status of the mirror in more detail.  You can
find the current ftpsync at:
http://ftp.debian.org/debian/project/ftpsync/ftpsync-current.tar.gz

Regards,
Bastian
