hash sum mismatch fpr ftp.se.d.o and ftp.nl.d.o

Hi
Since about ten hours back we've observed hash sum mismatch messages for
both ftp.se.d.o and ftp.nl.d.o.
Something fishy is going on somewhere.

When writing this dinstall has been running for 30 minutes on ftp-master
(timestamp 1397505123).

The mirror status page for ftp.nl.debian.org seems to report it being good (
ftp.acc.umu.se is noted as disabled though).

Hash Sum mismatch


(mostly a heads up)
