My web hosting also uses higher quality hardware for better performance and stability.
With 99.99% proven uptime, your website is going to be “up” and available to your users all the time.
VPS web hosting is more secure than share hosting because resources are isolated and there are much fewer accounts on the web server.
The web server is monitored constantly. If an issue comes up, most of the time I find and address an issue before my customers are even aware.
