What This Means

99% of 73 network tests from Oman failed to reach these services. Global baseline failure rate is typically 1-3%. This 96+ percentage point difference strongly indicates intentional blocking.

Signal

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.
