SaaS (Cloud) Company Reliability

Recently our SaaS vendor, Rally Software http://www.RallyDev.com, Project Management Software has been having issues today staying online and got me thinking about reliability of software offerings hosted on the cloud.

 Background: According to online resources Rally Software revenues are between 10M-20M USD and this company has been offering their software exclusively SaaS (Sofware as a Service) for at least 6 years. A decent sized company boasting a lot of Fortune 500 companies as clients.

 During today's outage I have to wonder; Where is their Disaster Recovery? What possible issue could they have that would prevent another set of server's with different internet connections from taking over the load and provide uninterrupted service? I can only sit and wonder while our team is losing time not able to co-ordinate effectively.
