grade evidence: hourly probes of /v1/ipv6-readiness. Availability, latency and protocol measure the operator's shared infrastructure and generalize across its products; the price check applies to the probed product. We now also probe one other product per hour, rotating; "live price we measured" shows what each answered.
Measures IPv6 adoption for an AS in a way that survives contact with reality. Counting v6 prefixes is close to meaningless on its own, because a single allocation can hold more addresses than the entire v4 internet, so a count of one is not a tenth of a …
What this grade does and doesn't measure: it scores the paid-request handshake — whether the service returns a spec-valid 402 payment challenge, how fast, and whether its price is honest. We do not pay these endpoints yet, so we do not verify that the paid response returns correct or complete content. Availability is a probe success rate measured hourly, corroborated by a second network path for this service.
