You might be amazed at the type of uptime some companies have. My former employer had a datacenter capable of running somewhere around a week without any external utilities (they were hardwired to three independent power utility companies) -- Enough power, food, water, and air in-building to run a week without restocking supplies. This isn't uncommon when you're talking backbone infrastructure. Honestly, a power failure is one of my least worries when it comes to full scale data centers. I'm only about $500 away from a generator at my house that would kick in and keep my servers up in the event of a power failure, but at this point none of my clients are interested in paying extra for that feature. Even doing it on a very small scale, 4-6 servers, isn't really that hard to afford. (I'm talking 10% more then their usual monthly fees for a year or two, not a lifetime commitment or a huge upfront cash outlay) -- Dave Warren, Email Address: [EMAIL PROTECTED] Cell: (403) 371-3470 Fax: (403) 371-3471 Toll free: (888) 371-3470 Vonage: (817) 886-0860 ICQ: 17848192 AIM: devilspgd Yahoo!: devilspgd MSN/PASSPORT: [EMAIL PROTECTED]
