When a user makes a request it is routed to the nearest CDN edge server, which significantly reduces the latency. A CDN allows all users, no matter the geographical location, to have fast loading content for an unquestionably improved experience.<p>According to BuiltWith, 66% of the top 10,000 websites are using a CDN (November 2018). This percentage has continually increased over the last 10 years due to the large growth of digital content consumption and high user expectations.
