Cloudflare

1. Site down, your name servers are down

I am having trouble reaching my website http://apifu.com/ from different networks. Are your nameservers working properly?

2. Why is my site coming from California?!

I’m in London, but looking at your IPs it shows that you are serving my website from California. Can that be right? Why is that? I thought you were supposed to serve my website from some places close to me?

3. Workers not applied

I've just added a Worker on the Cloudflare Dashboard for my website: it works in the debugger but doesn't work when I query the site. Why is that? Is there anything to activate or anything I could check?

4. Cloudflare Nameservers

How are Cloudflare's nameservers different from the DNS provided by Google DNS or OpenDNS? Can I delegate to Cloudflare nameservers while still using my host’s DNS?

5. Content not Being Cached

After activating Cloudflare on my site, I am seeing that resources on my pages are not being cached:

curl -svo /dev/null roskolniv.us
* Rebuilt URL to: roskolniv.us/
* Trying 104.16.27.128...
* Connected to roskolniv.us (127.0.0.1) port 80 (#0)

< CF-RAY: 1fa4b922fef517a4-SIN

* Connection #0 to host roskolniv.us left intact

Why is Cloudflare’s caching not working on my site?

6. Redirection based on user agent

I want to redirect visitor with specific user agent (*MSIE 8.0* for example) to a different page. It seems this is not possible with Cloudflare Page Rules. Is there any other way to achieve that using Cloudflare?
