It's expected that eventually things will go down, I've never once found a piece of software, server, person or traffic light which has performed at 100% for their entire lifetime, the best thing we can take from this however is response times.

Barely an hour from outage to being live again - I barely had time to fire an email to my colleagues and update our Twitter before it came back online - however, what's worrying here is that there was no fallback in place whatsoever, we will be hearing from the Cloudflare team soon hopefully to let us know what went wrong, but if they are half the company they purport to be, they will learn a lot from whatever went wrong today.
