OONI coverage in Macau

OONI's censorship measurements come from volunteers running OONI Probe on their own connections. Within one region, each provider and network (ASN, autonomous system number) may block different sites, so when only one or two providers are measured, blocking on the others goes unrecorded. This page sets OONI's measurement counts against APNIC's estimates of how many users each network has, to show how many users the measurements cover, which networks they concentrate on, and which networks have none.

The page is regenerated every hour and OONI's measurements are read every six hours. Taiwan is shown by default, with other regions as reference points; switch between them with the region list below. Each quarter's changes are written up in the quarterly reports.

Cards show the last 30 days, and the small charts show each day over the last 60. A lower share for the top two networks means the measurements are more spread out.

Networks with the most users

The ten networks with the most users by APNIC's estimates, against their share of measurements and the number of days measured over the last 30 days. Networks with many users and few measurements are where running OONI Probe helps most.

Where measurements come from

Each network's share of measurements over the last 30 days. When a few networks account for most of them, the rest can only be judged from scattered data.

Daily measurements

Measurements OONI Probe sends from this region each day, split by result. An anomaly only means the result differs from the control; confirmed blocking has been matched against known blocking patterns.

Users covered

The share of this region's internet users, by APNIC's estimates, on networks that had at least one measurement that day. One measurement is enough to count, so this is an upper bound rather than a sign that every network is measured enough.

How the numbers are calculated

  • Measurement counts come from OONI's aggregation API, across all tests, grouped by the day each measurement started (UTC)
  • Users per network are APNIC's estimates, derived from ad-based sampling and updated weekly
  • Network names come from the APNIC and RIPE NCC ASN name lists
  • A single measurement is enough for a network to count as measured; whether it is measured enough shows in its share of measurements and the number of days
  • Days without measurements are left as gaps in the charts rather than filled in

Help fill the gaps

  • Install OONI Probe and run tests on your own connection, on a phone or a computer. Mobile data and home broadband are usually different ASNs, so testing on both helps
  • The community's OONI Run link 10328 sets everything up in one tap; see the OONI Run v2 guide for the risks to consider before installing and what the list contains
  • ASN observation data analysis: why network diversity matters and how to read a single measurement
  • ASN Coverage: a command-line tool that downloads raw measurements and breaks them down by network type and blocking method
