Definitely smart to be delegating your DNS to the web-accelerator
company and a single point of failure, especially if you are not just
running a web-site, but have some other independent infrastructure,

>>>>>>CloudFlare's 23 data centers span 14 countries so the response took some time but within about 30 minutes we began to restore CloudFlare's network and services. By 10:49 UTC, all of CloudFlare's services were restored. We continue to investigate some edge cases where people are seeing outages. In nearly all of these cases, the problem is that a bad DNS response has been cached. Typically clearing the DNS cache will resolve the issue.

Yet, apparently, CloudFlare doesn't even support using any of their
services with your own DNS solutions.

And how exactly do they expect end-users "clearing the DNS cache"?  Do
I call AT&T, and ask them to clear their cache?
