In this post, we review selected Internet disruptions observed by Cloudflare during the fourth quarter of 2022, supported by traffic graphs from Cloudflare Radar and other internal Cloudflare tools, and grouped by associated cause or common geography.

We’re excited to present the Cloudflare Radar 2022 Year In Review, featuring interactive charts, graphs, and maps you can use to explore what changed on the Internet throughout this past year
