There is no single mitigation for any problem. Disaster Recovery planning will differ based on the nature of the disaster being mitigated against. Also, the problems you speak of apply to almost *any* hosted scenario, cloud or otherwise. Basically, you're under the impression that having your hands on the hardware guarantees you some sort of ETA. *Just this week,* we had a situation with our Cisco Unity server -- which is in our collocation space -- where it experienced a drive failure that rendered it unusable, even though its a mirrored drive. The 4-hour replacement took 8 hours due to several fiascos with IBM support, and turned out to be the wrong part. Another 4 hours got us the right part. Then, the rebuild and reimport of data failed on numerous levels and required speaking with no less than 8 or 9 technicians. 72 hours later, we're back up an running. This was with ONE server, and my team had physical access to the box, although that had little bearing on successfully getting it back up. We could not change the hardware in the box, because the install is keyed to specific part numbers, and the system refused to install to only one drive as an emergency. Imagine a larger ecosystem of complexity... The problem is not physical proximity. *ASB *(Professional Bio <http://about.me/Andrew.S.Baker/bio>) *Harnessing the Advantages of Technology for the SMB market... * On Fri, Apr 29, 2011 at 1:48 PM, Kurt Buff <kurt.b...@gmail.com> wrote: > Indeed.
