Problem solved. The culprit turned out to be a Cogent router in Dallas. Many thanks to Jason Beasley from XO for helping out with troubleshooting and escalating the issue. * Tore Anderson
I'm seeing blackholing on my inbound traffic from XO and their downstreams (notably CNN) via Cogent. Prepending towards Cogent changes my inbound path from 2828 174 39029 to 2828 3549 3292 39029 and it works fine, even though the outbound path is still via Cogent:
