What we cannot say

  • Who caused it — measurement data alone does not attribute this to any government, ISP, or other actor.
  • Intent — anomalous or unreachable measurements indicate interference, not a stated motive or a deliberate-vs-incidental determination.
  • Which networks — no specific ASN/ISP is identified for this incident.
  • The mechanism — we cannot state whether this was DNS tampering, TLS/SNI reset, an HTTP blockpage, throttling, or an infrastructure outage.
  • A confirmed duration — we report the observation window, not a verified start/stop of any block.
  • Sub-national scope — measurement is aggregated at the country level; we cannot localize to a province, city, or network segment.
