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)
