Despite what your lightning-fast Wi-Fi connection may indicate, the internet is not instantaneous. When someone visits your website, it takes time for content such as text, pictures, and videos to travel from the point of origin to wherever the website’s visitor is located. The further apart the two points are, the longer it takes for the content to be delivered.
Content delivery networks exist to expedite this process. Imagine your business is based in Boston and someone visits your website from San Francisco. If the content had to travel completely across the country, the website load time would be extremely long. CDNs improve this process by storing content on servers located throughout the country in data centers called “points of presence.”
