(who peers with cogent), and then pull the /24 some time later, that cogent holds onto the /24 and then bounces packets around in their network a bunch of times for upwards of 8-10 minutes until they finally yank it. this effectively blackholes traffic to my /24 for anyone that is using a path thru cogent.
Maybe running into some non-standard BGP Advertisement intervals inside Cogent's network? Might be running a lot of sub-ASes inside the confederation, and having to wait multiple advertisement intervals for full propagation. https://routingfreak.wordpress.com/tag/minimum-route-advertisement-interval/ -- Brandon Ewing (nicotine () warningg com)
