I've been rsyncing my local CPAN mirror from FUNET for years. A week or so ago, I started getting this:
rsync error: timeout in data send/receive (code 30) at io.c(171) [sender=2.6.8] rsync: connection unexpectedly closed (13002061 bytes read so far) rsync error: error in rsync protocol data stream (code 12) at /SourceCache/rsync/rsync-14/rsync/io.c(342)
