Greetings Outages.org recipients,
Since yesterday, 03-NOV-2014 around 07:12AM EST, two systems on separate
Time-Warner Cable (TWC) accounts have been experiencing intermittent and
severe packet loss between TWC in NYC and my network in Ashburn, VA.
I've run MTR to the equipment on TWC. The loss I see in that direction
is on the last two hops only. When I traceroute back to my network from
TWC, and see packet loss, it's between TWC and Verizon.
Does anyone have any insight into this problem that, for the moment,
appears to be between TWC and Verizon in the DC metro area?
Regards,
