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.
