Once you get into the counting of years (rather than days), it's all down to hardware. How long before that hardware needs an upgrade? Does your incoming power have fail-overs? I don't currently have any servers with multiple power supplies, so if anything like that goes bung, my server's down. Doesn't matter how quickly I can bring up an equivalent on a different hunk of hardware, the uptime's gone. But yeah. 300 years? Good luck. I don't think anyone's ever going to hit that. ChrisA
