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.
Sub-national scope — measurement is aggregated at the country level; we cannot localize to a province, city, or network segment.
Independent corroboration — this rests on a single source; treat it as a single-source signal, not a multi-source confirmation.
