Summing up their position, Level 3 said:

"To be lasting, business relationships should be mutually beneficial. In cases where the benefit we receive is in line with the benefit we deliver, we will exchange traffic on a settlement-free basis. Contrary to Cogent’s public statements, reasonable, balanced, and mutually beneficial agreements for the exchange of traffic do not represent a threat to the Internet. They don’t represent a threat to anyone other than those trying to get a free ride on someone else’s network."

So what has changed for Level 3? Unfortunately, they are now the one “trying to get a free ride on someone else’s network” and failing to “keep the interest of their customers paramount.”

“Such beliefs ignore the fact that the presence of a particular quality or skillset, or the appearance of natural aptitude, can have much more to do with subtle social signals and access to the resources and opportunities necessary to prove their capability. Often, “smartness” is used as a proxy for the ability to signal prestige and social status, and when used as a criterion for hiring, will effectively filter out individuals without access to such prestige, or who do not value such performances of status. Many who have had to make do with fewer resources have learned their skills in a context of greater constraint, though such resourcefulness may fail to stand out in an environment which offers little room for filling gaps in experience. In reality, people who arrive at mastery will do so by incredibly diverse means, with very different starting points, leveraging different strengths, and overcoming different weaknesses.” Manufacturing the Talent Shortage, by Dimas Guardado | Model View Culture

The email began by telling me I was being “too emotional”.

It proceeded to question my skills as a project lead and attempt to undermine a firm decision I had made by appealing to more senior developers.

It ended with a smiley face.

“Let’s pause and dwell on this for a sec: In fifteen hours of conversation that included 314 total interruptions, I observed a total of 13 examples of women interrupting male speakers. That is less than once per hour, in a climate where interruptions occur an average of once every two minutes and fifty-one seconds.”

Verizon has confirmed that everything between that router in their network and their subscribers is uncongested – in fact has plenty of capacity sitting there waiting to be used. Above, I confirmed exactly the same thing for the Level 3 network. So in fact, we could fix this congestion in about five minutes simply by connecting up more 10Gbps ports on those routers. Simple. Something we’ve been asking Verizon to do for many, many months, and something other providers regularly do in similar circumstances. But Verizon has refused. So Verizon, not Level 3 or Netflix, causes the congestion. Why is that? Maybe they can’t afford a new port card because they’ve run out – even though these cards are very cheap, just a few thousand dollars for each 10 Gbps card which could support 5,000 streams or more. If that’s the case, we’ll buy one for them. Maybe they can’t afford the small piece of cable between our two ports. If that’s the case, we’ll provide it. Heck, we’ll even install it.

But, here’s the other interesting thing also shown in the Verizon diagram. This congestion only takes place between Verizon and network providers chosen by Netflix. The providers that Netflix does not use do not experience the same problem. Why is that? Could it be that Verizon does not want its customers to actually use the higher-speed services it sells to them? Could it be that Verizon wants to extract a pound of flesh from its competitors, using the monopoly it has over the only connection to its end-users to raise its competitors’ costs?
