The internet uses caching technology at every level to speed up the exchange of constant data that is regularly used (for examples websites).
There are worldwide content deliver network that circle the planet storing duplicates of websites (or data). This allows users from any country to access website much faster.
Your browsers (Chrome, Firefox, and Edge) on all your devices (desktop, laptop, tablet, mobile) have caches that store the webpages you regularly view. Typically your browser cache stores text, logos, graphics and images for weeks.
Cache’s present a big problem when the website (or data) is updated. Cache’s take time to update (sometimes days). Browsers can be stuck with old information until they are manually cleared.
While we can clear our network caches after we make changes to a website. We have no control over the browser caches on your computers and devices. You need to clear these caches.
