I've seen some Cogent-Sprint congestion today also. About 10% PL at the
link.

We have smokeping's from our side showing 30%+ packet loss from us
(AS4307) to Verizon.
All I have gotten from Cogent is a canned response:
---
The latency and/or packet loss that you are experiencing to this
destination is due to occasional high traffic with Verizon. We have
repeatedly requested augments to these congestion points and hope Verizon
will comply soon. While this has been escalated internally to the CEO
level, we encourage you to also contact Verizon customer support with your
concerns and complaints. Their delay is a major impediment to internet
traffic overall and contrary to net neutrality requirements. Our peering
engineers will continue to address this on a daily basis until resolved.
---
It seems to have gotten a lot worse in recent days, to the point where we
have customers who are trying to access us from Verizon's network (i.e.
they have Verizon DSL, or via Verizon 3G/4GLTE) complaining they are having
a very hard to checking their email, etc.
Has anyone else been experiencing these issues? Or does anyone have more
information that what Cogent provided me in their canned statement?
