I have a VPS with our Ubuntu LoCo Team's blog, but I want to setup a message that says the server is down when it happens, like Reddit and Twitter does.
For example, if I restart the server or my VPS goes down, I want the user to load another page, from another server, saying the site is down and will be back soon.
I guess that can be done with redundancy, but I don't know anything about it to be honest. Is that possible and there is any tutorial about it?
I searched a lot, but since I don't know how to call this "feature", I don't really know what to look for.
Anyway, if it helps, I use Nginx, PHP-FPM, PHP-APC and Ubuntu Server 12.04. My DNS is hosted at CloudFlare Pro.
Thanks in advance :)
