Network Solutions outage?

Tue Apr 4 14:31:10 UTC 2006

We saw repeated withdrawals of 205.178.184.0/21, and it lasted well over 
an hour..

#show ip bgp 205.178.190.1
BGP routing table entry for 0.0.0.0/0

5 minutes later:

#show ip bgp 205.178.190.1
BGP routing table entry for 205.178.184.0/21

We were seeing the prefix re-appear for one provider at a time, then 
withdrawl.
