Long-term history
Before our monitoring: IODA archive
29 incidents · 10 blackouts · 11 partial outagesOutages in Cuba 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.
