Might be the first time I have ever seen that. Though in my case the "Host" is Cloudflare's own Pages service.

Yeah, I was shocked. Disbelief that the host was up, which is what usually happens when the cloudflare's page show up

They still blame the customers when you click on "Cloudflare":

> If the problem isn’t resolved in the next few minutes, it’s most likely an issue with the web server you were trying to reach.

In terms of probability looking at the history, it is correct. It's mostly me messing up with the web server.

I noticed that refreshing honesty too, not that the users did (our wifi is down fix it pls urgent)

That is really good to be honest!

I have Cloudflare running in production and it is affecting us right now. But at least I know what is going on and how I can mitigate (e.g. disable Cloudflare as a proxy if it keeps affecting our services at skeeled).

I searched my logs for errors for about an hour before figuring out the problem was not on my server :D

That page has special if/endif HTML comments to handle if your browser is IE 6, IE 7, IE 8...

And at the bottom:

What can I do?

Please try again in a few minutes.
