Hi,
This morning we've discovered that one of our IP's was routed somewhere
towards an ALTER.NET customer.
All the "experiments" i'm going to show you are done from
route-server.exodus.net.
a show ip bgp 193.231.236.41 show that the originator of the IP Block from
where 193.231.236.41 belongs is AS8708 (RDSNET ROMANIA).

Has anyone ever experienced this kind of problems? We've written to UUNET
Europe, and they've answered to us that it's a problem at UUNET USA. It's
been almost 8 hours since they replied to us, but the problem persists.
PS: If there are any technicians from UUNET on this list, please give us
a hand.
Thank you,
