The network capacity of a web server determines how quickly your websites shall open and exactly how many people shall be able to visit them simultaneously. Obviously, that isn't the only factor, but it's a rather important one. On the one hand, irrespective of how optimized a certain website may be, bad connectivity means slower loading speeds or maybe even service interruptions, especially when only 1 Internet provider is used to access the web server. Alternatively, a superb connection with lower capacity will allow only a small number of visitors to browse the website at the same time, while new visitors shall have difficult experience loading any content. In this sense, the success of your site is dependent not simply on the content, but also on the site’s accessibility and loading speed. Both of these factors are influenced by the connection the hosting server uses.
