Speedtests, SamKnows, and Fantasy vs. Reality at the FCC

Far too many people seem to think that when they go to Speedtest.net to test their connection, they get a number that has any bearing on reality. For most of us, it simply doesn't. This is true of other large tools for measuring connections. And it has important policy implications because the FCC contracted with a company called Sam Knows to measure wireline speeds available to Americans (I'm a volunteer in that project). Sam Knows explains :
SamKnows has been awarded a ground breaking contract by the Federal Communications Commission (FCC) to begin a new project researching and collecting data on American fixed-line broadband speeds delivered by Internet Service Providers (ISP's) - until now, something that has never been undertaken in the USA. The project will see SamKnows recruit a team of Broadband Community members who will, by adding a small 'White Box'’ to their home internet set up, automatically monitor their own connection speeds throughout the period of the project.
Unfortunately, SamKnows appears to be documenting fantasy, not reality. To explain, let's start with a question Steve Gibson recently answered on his amazing netcast, Security Now (available via the TWiT network). A listener asked why he gets such large variation in repeated visits to Speedtest.net. Security Now Logo Steve answers the question as an engineer with a technical explanation involving the TCP/IP protocol and dropped packets. But he missed the much larger issue. Packets are dropped because the "pipes" are massively oversubscribed at various places within the network (from the wires outside you house to those closer to the central office or head end). What this means is that the cable company (and DSL company, to a lesser extent) takes 100Mbps of capacity and sells hundreds of people 20Mbps or 30 Mbps or whatever. Hence the "up to" hedge in their advertisements. The actual capacity you have available to you depends on what your neighbors (cable) or others in the network (DSL) are doing. Dropped packets in TCP result often result from the congestion of high oversubscription ratios. This gets us into why Speedtest.net and Sam Knows deliver fantasy numbers.

Five Cities Denounce Verizon/Comcast Spectrum Deal

If you live in Boston, Baltimore, Albany, Syracuse, or Buffalo, you won't be getting FiOS from Verizon. Absent any public investment, you will likely be stuck with DSL and cable... like 80% of the rest of us.

Not long after Verizon announced it would cease expanding FiOS, we learned that Verizon was coming to an arrangement with the cable companies that would essentially divide the broadband market. Verizon won't challenge cable companies with FiOS and the cable companies won't challenge Verizon's "Rule the Air" wireless domain.

For a while now, the FCC has reviewed a potential deal for a Verizon purchase of Comcast's wireless spectrum. The possible deal involves multi-layered questions of anti-competitive behavior, collusion, and corporate responsibility. 

Along with many other interested parties, such as the Communications Workers of America, Free Press, Public Knowledge, and  the five towns are publicly opposing the deal. They have expressed their derision to the FCC but whether or not they will influence the result remains to be seen.

From a FierceTelecom article by Sean Buckley:

Curt Anderson, chair of the Baltimore City Delegation to the Maryland House of Delegates, expressed...outrage on the agreement the telco made.

"Under this transaction, Baltimore will never get a fiber-optic network, and the city will be at a disadvantage," he said. "The direct job loss will be the hundreds of technicians that would be employed building, installing and maintaining FiOS in the area. The indirect costs of this deal are even higher: the lack of competition in telecommunications will raise prices and reduce service quality.

And:

The deal, said Albany Common Council President Carolyn McLaughlin, "is not in the best interest of those who need to get and stay connected the most and is "a step backwards in bridging the digital divide."
