Hosting is hosting regardless of who does it. Outages will occur regardless of who does the hosting. The real problem is how to recover quickly when a problem occurs, and that depends on what the problem is.

The length of the outage is always the issue. Having redundancy is OK as long as it takes you less time to bring it up than it does to recover the primary.

Everyone thinks that disaster recovery is a simple, flick switch affair, which, when it comes to DNS and TCP/IP addressing changes as part of DR, is an absolute crock. It takes time for these changes to be recognised around the world so most times getting your primary working again is almost always quicker than moving to a failover.
