I posted this awhile back in the direct reports but haven't seen any response or activity on it. Some corroboration of my results from other locations might help. This is from SF.
I'm trying to play a game hosted on the east coast, and the packetloss is killing me. This happened for a few days last week, and then cleared up. Today it is back again.
The packetloss happens between hop 7 and 8 which looks like it is entirely within Comcast (hop 8 IP is listed as Comcast on arin.net although there is no reverse DNS entry).
I know the limitations of ping and traceroute, but the packetloss is consistent for any hop past #8, so I'm pretty confident that it's the link at issue.
I have ping results listed at the bottom from simultaneous pings of hops 7, 8, and 9. Hop 7 has no packetloss, and hop 8 has 18% packetloss.
