Last week we at Comcast reached some substantial milestones in our RPKI rollout (validation on inter-provider sessions, ROAs for our address-space). Jason Livingood and I collaborated on a blog post, FWIW. https://corporate.comcast.com/stories/improved-bgp-routing-security-adds-ano... Please forgive the somewhat less-technical public-facing verbiage. Thanks for all the support of people inside Comcast, particularly Courtney Smith, and also folks in the community on this long journey. (We have lots of address space spread over more than 20 regional networks as well as our Backbone network which made the ROA part a bit complicated. I issued over 9k ROAs or about a quarter of ARINs total.)
