Comcast's business internet support

Hi there - If someone from Comcast who is smarter than their business support team could contact me off list, that would be great. There appears to be very high consistent packet loss for last 3 to 4 days and that is affecting my internet,

You business support team keep insisting on sending an onsite tech. I explained that I don’t believe that will resolve this issue (There is no evidence of an issue with the lines or signal levels) and it’s a packet loss inside Comcast network, most likely aggregation/backhaul.

Thanks in advance.

Cheers,
Masood

The easiest way forward is to let them send the tech out. That's the script.

im guessing this is going to be one of those posts where mtr told him the ip of the CMTS or another inside hop has loss because it deprioritizes/rate limits ICMP :slight_smile:

Thanks, Seth! I got a quick response from someone at Comcast.

Nah this does not seem to be related to ICMP throttling. I do observe a significant service degradation when browsing/streaming various well known applications (feels like 56K modem :P)

There is a packet loss which is leading to excessive TCP retrans/dup acks.
