Lev,
There is some useful software available from the TSTG group at CERN
which can help localise problems like this. I intend to integrate
these tools into the GOC shortly after Easter.

Hi,
I think we have found the problem.
The IP Subnet 213.131.5.0/24 is not registered in the reverse DNS, we will
register the subnet within several days, and I hope the problem should
disappear.
Regards,
Lev.
