If someone knows a good AT&T routing problem contact, please let me know
offline.
Apparently in some cases the AT&T system routers in the business fiber
division stop routing IPv6 to customers.
I suspect some mid-level DHCPv6 larger block lease expiration issue, but
all I know for sure is that AT&T mid-level routers start returning
"address unreachable" errors for blocks of IPv6 addresses.
As expected there is no working customer service infrastructure at AT&T
to deal with anything other than customer modem issues and they're not
allowed to escalate.
If anyone has a contact, please let me know.
