Is there any way to host my site on two geographically separate servers? For instance, if one host goes down for any reason, a second host or server will keep my site live for visitors. Another way to put it would be...website.com is hosted with ABC hosting provider as well as DEF hosting provider. If ABC or DEF temporarily goes down, website.com is still accessible because the other host is still up and running, redundant web hosting if you will.
Thanks.

You can do this with a third-party DNS provider and a monitoring/failure switchover ("failover") option.

This is usually an extra-cost option, though some providers will provide some free with a package deal. I think my DNS provider gives failover for 3 domains with their 25-domain "business" package.

They monitor your website, and if it goes down, switch the DNS to point to the backup.

You need to set a small TTL (time-to-live) on DNS (say, 5 minutes) for this to work. Keep in mind that you will still leave a few users in the lurch.

There are other ways to do this, but this is perhaps the most reliable. Your site is being monitored and your DNS provided by a reliable distributed network, rather than from a single point.
