Indeed, network went down for some reason. Actually it went up, but I
can't see link going down in the syslog.

Oct 22 05:21:45 ovz1 kernel: eth0: link up, 100Mbps, full-duplex, lpa 0x05E1

this is openvz running in a xen hvm which was paused and resumed for
backup, most probably this is whats causing it.

Thanks for the hint.
