Is using Cloudfront for my CDN dodgey?

We are thinking of using Cloudfront to host our website images/css/js,

I realise the CDN would have excellent uptime,

but what if the public internet D开发者_运维问答NS goes down temporarily

(as it does sometimes, here in New Zealand we can't access international sites for a brief period), does Cloudfront rely on such a service?,

This would obviously cause the website to show, but it wouldn't be able to get the CDN assets..

You could probably use Route 53 in conjunction with CloudFront to get high-availability DNS. It's possible that CloudFront already uses Route 53, since they're both Amazon products, but I don't know for sure.
