    I`m just interesting - is it was NIC error, or cable was unplugged...

    This entry:

    May 4 12:13:40 Zeus kernel: e1000: eth1 NIC Link is Down

    Generally means the network cable was unplugged or the line was interupted somehow (ie connected to a downed router). It could be a fualty nic card though.

    I would ask your provider to replace the cable and possibly the nic card as well just to be on the safe side. If the problem still persists then at least those two possible situations can be ruled out.
