If all of the below features are properly implemented how the system failed for 5 Hours? Each cloud server VM should be in different physical (hardware) server. The "abnormal hiccup in the middle of file transfer" you are saying making no sense to me. How Everleap works How multiple Cloud Servers are utilized The load balancers constantly adjust traffic to balance it between all of the Cloud Servers available for your site. If a Cloud Server is ever down for any reason, the load balancer immediately routes all traffic to healthy Cloud Servers. This prevents most causes of web server downtime. Every site on Everleap has access to two Cloud Servers You get the benefits of multiple Cloud Servers for every site you host with us at no extra charge. If you run a site that would benefit from more than two Cloud Servers, they're available to add instantly. Even if your site only runs on a single Cloud Server, it's still redundant Your site can be instantly replicated on another server at any time. So even if you only run a single Cloud Server, in the event that anything goes wrong with that server, your site spins up on a new server and traffic is routed to the healthy server. All of that happens quickly and automatically.
