A few months ago, a complaint started popping up from users downloading or updating our apps: “Geez, your downloads are really slow!”
If you work in support, you probably have a reflexive reaction to a complaint like this. It’s vague. There’s a million possible factors. It’ll probably resolve itself by tomorrow. You hope. Boy do you hope.
Except… we also started noticing it ourselves when we were working from home. When we’d come in to the office, transfers were lightning fast. But at home, it was really, seriously getting hard to get any work done remotely at all.
So, maybe there was something screwy here?

…the problem was essentially gone. Comcast really did fix it. We were now able to measure our Comcast download speeds in megabytes/second instead of kilobytes.
According to Comcast, two primary changes were made:
Comcast added more capacity for Cogent traffic. (Exactly as we suspected, the pipe was full.)
Cogent made some unspecified changes to their traffic engineering.
Here’s where I have to give Comcast credit where credit is due: they really did care about this problem, and they really did work quickly to make it go away.

Much as people rag on around here, they did the right thing in this story.

Cabel Sasser got reports from customers - and then discovered himself - that downloads from Panic were really slow. So they put out a script that would let people download a sample file, and recorded which ISP they were with, and at what time:

Nuts. The problem reports we’d been hearing were indeed a real thing.

Our downloads really were slow — but seemingly only to Comcast users, and only during peak internet usage times. Something was up.

At first we thought, maybe Comcast bandwidth is just naturally more congested in the evening as people come home from work and begin streaming Netflix, etc. But that didn’t explain why the connections to our Linode control server from Comcast, during the exact same time windows for each tester, were downloading with good speeds.

We wondered, is Comcast intentionally “throttling” Cogent customers? And if so, why?</p>


This is a terrific story of internet plumbing.
