Summary
Cloudflare’s Q2 disruption summary said internet outages from April to June 2026 were driven by government shutdowns, damaged infrastructure, cable cuts, storms, earthquakes and power failures.
Iran restored nationwide access on May 26 after an 88-day shutdown; traffic reached 40% of pre-shutdown levels the next day, later peaking near 90% before settling around 59%.
Government actions also included 10 exam-related shutdowns in Sudan and three in Iraq, while drone-strike damage to AWS facilities in the UAE and Bahrain kept traffic to a UAE cloud region depressed since March.
Infrastructure and technical failures caused sharp local disruptions: a DENIC DNSSEC error broke .de lookups for hours on May 5, and a June 21 fiber cut near Saint Lucia pushed Karib Cable traffic close to zero and cut national traffic about 60%.
Natural events rounded out the quarter, with Guam traffic dropping as much as 80% during Super Typhoon Sinlaku, Venezuela’s June 24 magnitude-7.5 quake hitting multiple ISPs, and a June 27 Tanzania blackout cutting traffic for at least five hours.
