12 incidents · 5 blackouts · 1 partial outages

Outages in United States detected by IODA (Georgia Tech) between January 2022 and the start of our own monitoring: drops in the country's internet routes (BGP) or in its reachability from IODA's active probing, compared with the day before. Each is checked against IODA's signal; small dips are left out.
