105,149 observations across 25,545 unique endpoints this month. Spec-compliant 402 rate: 60.2% (-9.1 pts MoM). Latency p50 (compliant): 261ms (+48.0 MoM). No self-reported metrics - every number below comes from real probes.
Share of probed endpoints returning a spec-compliant 402 challenge, per weekly full-census round (daily top-500 probes are excluded here: a biased sample would flatter the rate).
