How fast a site is going to open would depend not just on the Internet connection of the website visitor, but also on the online connectivity of the server in which the internet site is hosted and on the network infrastructure - routers, server network card, etc. Slow connection or hardware which is unable to deal with a high volume of inbound and outgoing traffic might have strong influence on the user experience of your visitors and the performance of your internet site because people will most probably see error messages that the website is not available or it will take some time for your content to load. If this kind of a thing occurs, it is not very likely that the site visitors shall revisit the internet site. For this reason you have to always confirm the connectivity of any hosting server that you obtain and not only the main hardware components like hard drive, cpu and physical memory.
