Cloudflare Error: Sorry, this website is offline.
« on: September 16, 2010, 02:22:46 PM »
I am beta testing for CloudFlare and today I am trying to visit my web site but an error message appears instead:

Quote
PAGE NOT FOUND IN CACHE

Sorry, this website is offline. In addition, no offline snapshot was found for your requested resource.

You can exit offline browsing now by retrying the live version.

Acceleration and Protection by CLOUDFLARE.

Anyone else experience this and know how to fix it?

Well the problem has resolved itself.  Maybe it was the DNS taking longer than usual to fully propagate.

( UPDATE: Well actually it is happenning again.  Any ideas guys? )

Hi Dyna,

Sorry this is a few days late  It was probably a DNS propagation issue but this information from our Wiki might help if it surfaces again (I would also recommend making sure you whitelist our IP addresses as well).

There are three main reasons why you may see a black CloudFlare page with the text "Sorry, this website is offline".

1) You have blocked one of CloudFlare's IP addresses on your server or you have a .htaccess rule in place that limit connections from some IPs. CloudFlare acts as a proxy, so it is important not to block requests from its IP addresses. CloudFlare's IP range includes:

66.225.125.0/24

204.93.240.0/24

204.93.177.0/24

204.93.173.0/24

199.27.128.0/21

If you have blocked any of these IP addresses, you should remove them from the list or whitelist them.

2) You are running some sort of protection software like BadBehavior or mod_security that are blocking CloudFlare's servers access to your server.

3) Your backend server is down. In this case, CloudFlare will serve a page from its cache with an alert at the top telling your visitor they are in offline browsing mode. However, if CloudFlare does not have a page in its cache, then your visitor will see this page.

Thanks for participating in the beta!

Thanks for the info.  I know the server was not down, so reason #1 or #2 must be the case.  My server does run mod_security, and along with the problem only occurring a couple times on a temporary basis, I am leaning to reason #2.  The ruleset we use is the standard modsec2 default.  I will have to check through the log files to see what could have possibly set it off -- if in fact it was the case of too many mod_security violations triggering the csf/lfd to ban the proxy for a while.

Thanks for your new service.  I am sure it will be successful!

Hi dynaweb,

Glad to help. Please do let us know if you have any questions or problems down the road.

FYI: I would also recommend following us on Twitter (if you have a Twitter account) because we update any potential service issues their to keep folks informed. We've had a few minor blips over the past few days that could have contributed to what you were experiencing.

I have a twitter account but don't use it that much.  What I will do is use the RSS feed from your twitter link and use RSS Dog to post the latest tweets here on this page.  Maybe that will help for reference for others who stumble across this page.
