How quickly a site is going to open is dependent not only on the Internet connection of the website visitor, but also on the online connectivity of the server where the site is hosted and on the network infrastructure - routers, server network card, etcetera. Slow connection or hardware which can't deal with a high volume of inbound and outbound traffic may have direct impact on the user experience of your customers and the overall performance of your internet site since people will most likely see error messages that the site isn't available or it shall take some time for your content to load. If this kind of a thing takes place, it's not very likely that the guests shall revisit the website. That is why you need to always examine the connectivity of any hosting machine that you purchase and not just the main hardware components which include hard drive, processor and physical memory.
