Hi!

reaching 2001:67c:1562::13-17 (security.ubuntu.com) via tserv6.fra1.ipv6.he.net or tserv11.ams1.ipv6.he.net is not possible. Even a ping does not work, but pinging the IP from a server with a "real" ipv6 address works.

I've tried all IPv6 address from:

$ host security.ubuntu.com
security.ubuntu.com has address 91.189.91.13
security.ubuntu.com has address 91.189.91.14
security.ubuntu.com has address 91.189.91.15
security.ubuntu.com has address 91.189.91.23
security.ubuntu.com has address 91.189.91.24
security.ubuntu.com has address 91.189.92.200
security.ubuntu.com has address 91.189.92.201
security.ubuntu.com has address 91.189.88.149
security.ubuntu.com has IPv6 address 2001:67c:1562::15
security.ubuntu.com has IPv6 address 2001:67c:1562::17
security.ubuntu.com has IPv6 address 2001:67c:1360:8c01::19
security.ubuntu.com has IPv6 address 2001:67c:1562::13
security.ubuntu.com has IPv6 address 2001:67c:1562::16
security.ubuntu.com has IPv6 address 2001:67c:1360:8c01::18
security.ubuntu.com has IPv6 address 2001:67c:1562::14

Only 2001:67c:1360:8c01::18 and 2001:67c:1360:8c01::19 work, the others don't.

See the other thread where Occaid/TowardEX is having routing issues at their Internap/XO upstream handoffs:

https://forums.he.net/index.php?topic=2911.15

An MTR from inside HE's network shows it gets into XO's network, then dies where it hands off to Internap who gets the routes from Occaid/TowardEX, or it used to. Now going via Telia, it still dies inside Internap's network. Not an HE issue.

FWIW, I tried the problematic Ubuntu destinations from a Comcast provisioned IPv6 network, and they work there.  Is someone pursuing/reporting this to the guilty party(ies)?
