How we check
Earthquakes come from USGS, storms, floods, eruptions and wildfires from GDACS. For each one we look at the countries it hit: every national internet outage our probes and IODA measured, every regional outage near it, and every large power outage.
An outage counts as a disruption when it reached "partial outage" or "blackout" and started within 24 hours. Before 16 October 2026, when our own probes started, we use IODA's measurements.
