Writing on bandwidth, price and proof
Technical notes, market structure, and the measurements behind everything we claim. No launch posts, no thought leadership.
9 PIECES · NOTHING GATED
Measurement
A tenth of the price is not a discount, it is a different market
Cutting the unit cost of a gigabyte by ninety percent does not win you the same customers more cheaply. It hands you customers who could never afford the category at all.
Supply
Meta v. Bright Data, and the day logged off scraping got a great deal safer
A single summary judgment in a California district court did more for the legality of public web data collection than a decade of argument. Here is what it actually held, and what it did not.
Market structure
Underwriting a counterparty on nothing but its payout history
You cannot audit a demand platform’s balance sheet. You can measure whether it has ever actually paid, which turns out to be the only input that predicts anything.
Market structure
Securing a payout by taking the concentration out of it
Most sellers lose money to correlation, not to default. One buyer, one carrier, one country, one currency: any of them can zero a month on its own.
Market structure
Economies of scale in a business with no marginal cost
When the marginal gigabyte is nearly free, scale stops being about buying cheaper and starts being about arriving at a fuller pipe. Some costs still refuse to fall.
Engineering
Reading a partner runtime we do not have the source for
Onboarding a demand platform means knowing exactly what its binary sends. Three tools do most of that work: a process buffer dumper, a symbolic execution engine, and a string materializer.
Engineering
BLAKE3, and proving a gigabyte actually moved
Billing on delivered units means both sides need a receipt neither has to trust. A hash tree gives you one, and it turns out to be nearly free.
Engineering
Futex storms, the OOM killer, and threads that never wake
An exit host running four hundred partner containers fails in ways that never show up in CPU graphs. Three failure modes account for almost all of it.
Market structure
Why proxy bandwidth costs what it costs, and why that number is wrong
The unit price of a gigabyte is almost entirely a function of how full the pipe already is. Here is the arithmetic, with the numbers we actually run.
One letter a month, and only when we have measured something worth sending.
