Like most infrastructure, the Internet's fragility is easy to overlook — as long as it's working. When it fails, its complexity comes into full view. Cloudflare is in a unique position to detect and document the moments when one of the interrelated systems the Internet depends on breaks down and connectivity suffers as a result. Each quarter, we summarize the disruptions we detect and annotate on Cloudflare Radar.

In Q2 2026, Super Typhoon Sinlaku just north of Guam caused the longest outage, while government-mandated shutdowns during exam periods in Sudan were the most frequent. Iran restored national Internet access, reconnecting its citizens to the global network after an 88-day blackout, even as damage from drone strikes continued to disrupt AWS infrastructure elsewhere in the region. Finally, a cable cut in Saint Lucia and the distribution of faulty DNSSEC signatures in Germany underscored the fragility of Internet infrastructure, but also the remarkable stability these regional and global systems maintain when operating normally.

Here we will walk through the most significant Internet disruptions we observed in the second quarter of 2026, drawing on traffic data from Cloudflare Radar to show how each unfolded and what it meant for users on the ground. As always, this is a summary of notable, confirmed disruptions rather than an exhaustive list; a fuller view of detected traffic anomalies is available in the Cloudflare Radar Outage Center. 

Natural disasters and electricity cause disruptions in Guam, Venezuela, and Tanzania

Super Typhoon Sinlaku, the strongest storm of the 2026 Pacific typhoon season so far, tracked through the Mariana Islands in mid-April, passing just north of Guam. Though the island was spared a direct hit, the storm brought tropical-storm-force winds, knocking out power across Guam and disrupting water systems, which had a direct impact on Internet connectivity. Traffic from the territory fell as much as 80% below expected levels from April 13 to 14. 

Two months later, on June 24, two major earthquakes struck northern Venezuela within about a minute of each other, in Yumare and San Felipe, followed by an aftershock
