Cogent packet loss to Verizon in San Jose

Anyone from Cogent around?  Normal support channels aren't getting me
anywhere.

We have been seeing consistent packet loss to Verizon over Cogent in San
Jose for several days:

We have had to route some customer's traffic out through our alternate
provider (AS20115), as their VPN's were borked by the packet loss.
