Cloudflare's quarterly review of disruptions seen on its Radar service counts 49 between July and September 2026. Government-directed shutdowns were the largest group with 19 incidents, 18 of them scheduled exam shutdowns in Iraq. Power outages came second with 14 incidents across 10 countries, and natural disasters accounted for five.

Cuba had four power-related outages in the quarter — on 6 July, 14 July, 3 August and a three-day blackout from 18 to 20 September — with traffic falling between 18% and 59%. In Honduras a power failure at an interconnection facility on 10 September hit at least 11 major providers and cut national HTTP traffic by 63% for about three hours. In Sevastopol, a power outage on 5 July caused an eight-hour blackout with traffic down 98%, and drone strikes on energy infrastructure on 12 August caused a ten-hour disruption. On 13 August a cooling-system failure at a data centre in Phoenix caused a near-total drop in traffic from the registrar Namecheap.

Natural disasters included Super Typhoon Bavi in Guam, a magnitude 7.4 earthquake in Colombia that disrupted connectivity for four and a half days, and flash floods in Nepal on 26 August.

What it means

The recurring lesson in the report is concentration. Honduras lost most of its traffic because exchange was concentrated at one facility; the two providers that stayed up appear to rely on infrastructure outside the country. The Phoenix incident is the same point at company scale — one site, one cooling system, one provider dark. Cloudflare's numbers come from traffic to its own customers, so they show where connectivity fell, not every outage that happened.
