Redundant web hosting options..?? How to keep site from going down..??
Posted on 2013-12-31
Over the past few years I've been through about 10 different hosting companies including Media Temple, Rackspace, HostGator, VPSZone, Bluehost, and more. I've had issues with down time with every one of them and I've come to the conclusion that 99.9% uptime is total BS by all of them.
As such, I'm trying to figure out how I could setup a backup hosting company to kick in when 1 goes down. I'm not sure how I would do that, though, because I don't know enough about DNS and how to set something like that up..??
As it stands now I'm on a VPS server using my own nameservers, and my domain name is simply configured to use these name servers, which point to the IP addresses of my VPS.
If I had another hosting all setup it seems like the only way to switch would be to update the IP addresses of my nameservers so they hit the backup server, but then of course that can take time to propogate and by the time that happens the original one would probably be up again.
I really haven't been able to find any info about this sort of thing Googling, which is surprising me. I guess I'm not using the correct search terms or something.
Any information on how I can make sure my sites NEVER go down would be greatly appreciated. Thanks!
