Maintenance outage last night, PD woke up shortly afterward and collected
a /56, no joy after that -- egress traffic gets where it's going, ingress
is dropped not far into 701. Only visible covering route is the
2600:4000::/24 aggregate, both externally and via Verizon's looking glass.
It looks like there are several reports of the same issue in other areas
over the last couple months, where those that work have covering /36s
advertised externally and the broken ones don't, e.g. no
2600:4041:2000::/36 here.
Happy to follow up off-list, if so inclined. Thanks!
