I'm looking for a simple solution to increase my website's uptime. My website consists of simple HTML and PHP pages with no database. Right right I use paid shared hosting and I sometimes find that my website is not loading.Would it be possible to put my website on two hosts and in case the main host is down the other one would get used? What is the best way to set this up? 
Having 2 hosting accounts in case one of downtime?
