Re: IPv4 Subnet 23.151.232.0/24 blackholed?

Neel,

Carriers rebuild their prefixes lists once or twice in a 24 hour period. 
Considering that you just got the block today and is in ReliableSite's 
AS-SET, you just got to be patient.

Having announcements propagated immediately either sounds like it 
happened a day after you gave them the LOA, or they have unfiltered 
transit circuits, which is worrisome.
