Over the last two days, Cloudflare observed two events that had effects on global Internet traffic levels. Cloudflare handles approximately 10% of all Internet requests, so we have significant visibility into traffic from countries and networks across the world.
At approximately 4:50pm local time (8:50am UTC) August 15, a major unexpected power outage hit the island of Taiwan with a significant amount of its power generation facilities going down.
Sometime before midnight Monday (UK local time) a ship dropped its anchor and broke, not one, not two, but three undersea cables serving the island of Jersey in the English Channel.
Last Friday the popular DNS service Dyn suffered three waves of DDoS attacks that affected users first on the East Coast of the US, and later users worldwide.
Today there is an ongoing, large scale Denial-of-Service attack directed against Dyn DNS. While Cloudflare services are operating normally, if you are using both Cloudflare and Dyn services, your website may be affected.
