Connectivity exposure of listed companies

Each location is compared with the other locations in its country over the trailing twelve months on two things: working-hours latency (the median across Monday–Friday office hours, local time) and outage exposure (hours above the location’s own baseline, plus the longest run). Critical means both sit in the worst fifth, Stressed means one does, Watch means a degrading trend or thin data, Sound means neither.

A company’s exposure level follows its share of Critical and Stressed locations: Critical at 40% or more, High at 20%, Moderate at 10%, Low below that. Ranks within sector, country and index are computed only for companies with at least five locations that pass the data-sufficiency gate.

The priorities are the three locations contributing most to the Critical and Stressed share, weighted by how many of the company’s assets sit there; each names the metric behind it. The district table gives one value per district: the share of all listed-company locations there that are Critical or Stressed.

32,299 of the 53,310 companies carry the level “Insufficient data”: fewer than five locations pass the gate, so they have shares but no level and no rank.

“Anomaly” at three median absolute deviations on an unscaled baseline flags roughly one hour in ten in well-measured countries, so the buckets are relative rankings within a country, not absolute outage counts.

Asset locations are inferred from the parent’s IP ranges, headquarters and subsidiaries, not from a verified asset register; the index memberships come from public constituent lists. The measurement records timing, depth and shape; it names no cause.
