I've never really understood that argument. Assuming that your site is totally down when your server goes down and that you rely on jquery so heavily that loosing it essentially renders your site unusable it doesn't seem to matter how much better google is at delivering content than you are. If you can manage an uptime greater than 50% the likelihood is that your server and google will be down at different times so the downtime is additive.
