That's Cloudflare's Bot protection. You should have never gotten that. What IP did you try coming from if you don't mind sending so I can send to them to have them look into it.
I've not heard of anyone else having been caught by that (other then bots) which makes me wonder why you got caught in it.
P.S. if you go back to site you will see the "innovative" or "visionary" is a joke :)
Wow, trying to get back up right now, hit publish and drove home to get a call from partner that site is down. :( Next time I'll make sure to pay attention.
Thanks
