Are there any providers that Comcast doesn't regularly run hot? Seems like no matter who I deliver through at some magical point in the evening they start spiking jitter and a little loss. Almost like everyone hits PLAY on netflix at the same time. -shac
Hi Shacolby Can you share some mtr results to Netflix, Google, etc ? Curious to see how bad it is really. On Tue, Jan 31, 2012 at 8:50 PM, Shacolby Jackson <shacolby@bluejeans.com>wrote:

Some datapoints based on ~500mb constant UDP telemetry data feed (total) spread across many different comcast endpoints. All Cogent -> Comcast. Even though there's heavy forward error correction provisioned to accommodate 5-10% packet loss, it's hardly used. In fact, packet delivery is incredible impressive to comcast. Loss is well below 0.01% and often involves another zero in there, too. It's one of the best consumer access networks I've seen and I give them a huge thumbs up for it. Needless to say, I can't back up the same stats against some other carriers (Verizon being the biggest offender, with their congestion being localized to the ATM/DSLAM level and sometimes very high based on my metrics and sampling). That's why the FEC is there. On Tue, Jan 31, 2012 at 8:20 AM, Shacolby Jackson <shacolby@bluejeans.com>wrote:

You could try Cogent, AT&T, or Savvis, though they'll probably fill up now that I've mentioned it. Drive Slow (like a download going over Comcast-GBLX), Paul Wall
