From responses I received, I have gotten a number of different answers. Some are seeing our routes from 6128, some from 46887 and a few from both. The response from Eric though was typical. Showing the IPv4 prefix only from AS6128, but the IPv6 from both 6128 & 46887.
I am guessing that 46887 might be set with a community to not export our IPv4 prefixes except to direct peers? Anyone directly peered with 46887 that could see the community for 129.77.0.0/16 and verify? ---- Matthew Huff | 1 Manhattanville Rd Director of Operations | Purchase, NY 10577 OTA Management LLC | Phone: 914-460-4039 aim: matthewbhuff | Fax: 914-694-5669

One of our upstreams is apparently having problems, although they don't appear to know about it. I've seen an alert at BGPmon.net about our prefixes being withdrawn, and I can't locate our prefixes through that provider on any routeviews. Can someone check to see what ASPATHS you are seeing for our prefixes?
129.77.0.0/16 2620:0:2810::/48
We should be advertised via AS6128 and AS46887
