Level 3 Boston (Comcast NY) handoff packet loss since 11AM EST
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.

You'll notice that there is no loss beyond that router, only at that router. Routers are in the business of routing packets, not of responding to mtr, traceroute, ping, etc. More detailed clue is at http://www.broadbandreports.com/faq/toolquestion/Packet_Loss_Test__Line_Qual... I do not see a problem here, and neither will Comcast or Level(3). What made you think there was an issue in the first place? -r <ekagan@axsne.com> writes:

Your problem looks very local to me (as in, between you and your CMTS). Have you checked with your neighbors to see if they are having problems too?

Did you notice that the received packets and %loss at hop 12 drops back down to that at hop 10 and doesn't significantly change after that? The problem is probably between hops 1 and 2. Antonio Querubin whois: AQ7-ARIN
