I use Cloudflare in all of my websites, some of them get a decent amount of traffic.
As my hosting is still based out in the UK, it helps when my users are mostly in AU/NZ.
However, this morning and I fat fingered, deleting our Cloudflare link/account making about an outage for an hour.
So I suppose I would love to ask the tech experts here if you guys also use Cloudflare in your websites.
