A couple years ago our org made a big push to have our routes and our downstream customer routes RPKI valid. It's good to see the high adoption rate. It looks like ASPA is now available for ASN path validation. Probably should look at adopting ASPA at some point here.

Agreed, the post has a section on it: networks publishing ASPA records went from 131 to 3,272 in a year, mostly as each registry shipped signing tools. Still early, though. So far published records can verify about 3.5% of observed routing.
