Any "standby" backup solution for LEB?
Let's say I have one LEB in US and another one in UK. And I would like to host my website example.com on them.
My goal is simply like this: if either vps is down, users can be re-directed to the other one automatically. i.e. they can still type the same address example.com. in their browsers.
I am not looking for a performance improvement solution by directing the users to the closest/best server like CDN does, just want an automatic standby backup solution on low end vpses to achieve almost 100% uptime.
Is it possible? Can anyone point me to the right direction? Thanks
