Utilities such as electricity in many countries have an amazing 'uptime'. So much so that we tend to take it for granted that it is there. As part of an overall security plan, the assumption must be made that it may not be there. Phone companies use large batteries that are backed up by generators. Larger ISPs follow the same technique. In your firm, make sure you check the manufacturers rating for battery life of your UPS systems. PDA's lose all data if they completely discharge. Sealed lead acid batteries that need to be swapped out according to the makers recommendations usually run security alarms.
Do your ISPs have backup servers (and even backup sites)? If you depend on an ISP for external web-hosting of an e-commerce site, you should know the answer to this question.
