Do you use cloudflare?
 

Do you? Why?

DNS latency.

thought about it

Make sure you have your website DONE. Their caching will often not update and a few times the cache wiped my site and wouldn't reload back to their servers.

If I post to a wordpress blog it might not show the post for hours, a day or days to my surfers...

Well, I think it depends on what you cache, really... but I remember screwing one of my sites (was not loading at all) by using cloudflare some time ago. I just decided to open itheir site and it looks totally different now. Has anything else actually changed?

I tested it on a blog and had the same problem :(

I brought that test to a close pretty quick

What cache level were you using? I would use the most basic one for a dynamic and frequently updated site.

used quick cache ,never investigated further,as soon as the prob started I reverted back using my own nameservers

So, I take it it is only good for static sites? :D

yes and there is an additional drawback you will have no stats....

the plus is no dos attacks no brute force attacks...proxies dont get through

You can do similar things with ipv6

Server logs are no stats? :1orglaugh Besites, i think they had GA integrated.

Using it on forums with no problems.

Forums sounds like requently updated sites. So it works for you? What caching do you use? Free account? Paid?
