Mailing List Archive: Level 3 Boston (Comcast NY) handoff packet loss since 11AM EST

I had just reset the MTR counters, sorry. I have been getting bounced
out of apps all day. Here is an MTR running for the last 30 minutes.
Smokeping is also showing 4.37 avg loss, 44.41 max loss and 9.53 current
loss (png attached if it goes through ?)

Thanks
Eric

FYI In case someone can get this to a clue-ful individual. There was
been severe packet loss at Hop 11 below since 11AM EST this morning
leaving Comcast Mass network out through Level 3 NY/Boston.

I tried to report to Comcast (Request Summary: ID: 6863600) and was met
with less than pleasant clue. So much for being a good net'izen. I
agreed my "connection" was fine, but past that there was an issue. If
there is actually a way to report to Comcast NOC, please advise.

I've also reported to Internap from my side so they can investigate as
well.

Thanks
Eric
