We had power on the canary islands (belong to spain, but located in the atlantic ocean ~80km west of Africa) since it is an independent grid. But couple of hours into the blackout (starting 5-6pm local time), internet issues occured - with confirmed multiple landline providers going offline (Digi, Movistar) while others seems to continue to work (Vodafone). Also some cellular 5G were affected, otheres continued. Interested to see the postmorten - I suspect after 8-10h the data center's diesel generators on the peninsula that route the traffic ran empty. Internet operation resumed during the night (for me around 1am).
