How quickly a site is going to open is dependent not just on the Internet connection of the site visitor, but also on the connection of the hosting server where the website 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 outgoing traffic may have direct impact on the user experience of your site visitors and the overall performance of your site since people shall most probably see error messages that the internet site isn't available or it shall take a long time for your content to load. If this sort of a thing occurs, it is not very likely that the guests shall revisit the site. That is why you should always confirm the connectivity of any hosting server that you buy and not only the main hardware components such as hard drive, central processing unit and physical memory.
