I used to think that Data Center Downtime was serious business, but I've come around to believing that it shouldn't be. If your data center going down is a problem, then you don't really have a very robust failover plan.
If, instead, you _plan_ for the Data Center to go down, and treat a data center failure as a trivial issue, then your DR plans start to become significantly more robust.
In particular, the companies that I admire are ones that routinely swap, on a routine basis, their DR and production facilities - and when a production data center goes down they don't even bother to wait - they just light up the DR center and are back in business.
Most of the SaaS Financial Hosting companies (Oracle Financials) that I've talked with will provide you with that feature.
