I'm still waiting to hear from the upstream re: your transit issue. We noticed that Viagenie has a direct IP assignment from ARIN. There may be an RADB issue that is getting the route caught in the DT filters. At this point, it's just a matter of waiting for DT to get back to us with the results of their peering router checks.

Our DTAG contact has gotten in touch with me and indicated that the IPv6 filters that are in use on the peering side are rather stringent. I've asked him to indicate which filter is catching the viagenie.ca route and let me know. I will let you know what he comes back with.

It seems to end on an NTT address without error.

We do have a peering with NTT. The last address is the last hop just in front of our web server. Don't know why it doesn't reach the web server, but I wouldn't care too much about that part. The real problem is that our /48 is absent from the IETF's transit routing table.

Tata seems to see it with 3 prepends but I haven't spotted that outside their network.
http://lg.de-cix.net doesn't seem to know the prefix at all either and that has quite a few peers.
Seems there is a bigger fish to fry on global visibility for that particular prefix.

Our friends at DTAG and HE have resolve this issue and we now have the ipv6 route to viagenie.ca.

Verified the IPv6 address is reachable from the Internet. Verified BGP route in the main RIB on our Juniper's. At this point, I've got an email out to DT to check their routes as the "no route to host" message is coming from our BGP peer.
