Oh, I thought you were talking about the apache module!

Well I used CF for 3/4 months now.. I know how it works. :)
And also if you disable all the performance/CDN/compression stuff (that works well though) it's useful as a DNS manager.

But if you disable all that stuff, it seems like you're not using all the stuff it's (supposedly) useful for... in which case you might as well not bother and use a separate DNS service.

In fact I said that those things work well though ^_^
And yes maybe it's better to use a separate DNS service if you don't use their primary stuff, but you have for free their reliability, their infrastructure and you have your IP/hostname "masked".

That's the thing, though, it doesn't work nearly as well as you make it sound like - so many people have so many problems with it. Their infrastructure does not sound particularly reliable from all the reports I've had.

Reports about downtimes, slownesses, or problems with "performance features" that cause problems?

All of the above.

Yeah, especially downtimes and slowness. A forum I was admin on before it shut down had it installed, but the other administrator deleted Cloudflare in the end, because such issues. After that, the forum ran fast again. I'm really glad I don't use it myself.

I'm not payed to defend them ( :P ) but I have more than 10 websites with CF and I had issues only once or twice. I really like their system..
