Presumably ICMP probes - those are frequently rate-limited as
counter-measures you realize? And which Verizon? 701 clearly shows it
in its tables and packets go there. Since your mtr or whatever shows the
traffic reaching a GBLX address, so you likely want to reach out to them.

What does your table say? How does that compare to data in RIS, route-views,
etc? Independent investigation with table data -if your concern is the
state of someone's "routing"- would help.
