What is CloudFlare?

  • CloudFlare is a performance and security service that we provide to our customers. On average, a website on CloudFlare loads twice as fast, uses 60% less bandwidth, has 65% fewer requests and is way more secure.   


What is the association between TurnKey Internet, Inc. and CloudFlare?

  • CloudFlare is a third-party vendor that is offering the CloudFlare service to TurnKey Internet, Inc. customers through a partnership.


How does CloudFlare’s technology work?

  • CloudFlare is a CDN (content delivery network) with a security layer. Once a website is part of the CloudFlare community, its web traffic is routed through CloudFlare’s global network.
  • CloudFlare’s network stores copy of static files closer to web visitors, which means they are delivered more quickly than before. CloudFlare caches resources such as CSS, JavaScript and images. CloudFlare’s technology automatically decides which resources to cache based on file extension names so there is zero-configuration. CloudFlare also does compression for every request.
  • CloudFlare’s network also blocks threats and limits abusive bots before they hit the server, which means less wasted bandwidth and server resources.


Where are CloudFlare’s data centers located?

  • CloudFlare’s network currently has 12 locations where it does caching and traffic filtering:
  • Six in the US:
    • San Jose, Los Angeles, Chicago, Washington, New Jersey, Dallas
  • Three in Europe:
    • Amsterdam, Paris, Frankfurt
  • Three in Asia:
    • Hong Kong, Singapore and Tokyo


What types of websites can use CloudFlare?

  • Almost all websites can use CloudFlare. CloudFlare works for both static and dynamic websites.
  • CloudFlare is not suitable for websites that stream video or audio directly from their origin server. If a website uses YouTube or Vimeo for the videos embedded on your website, then that is compatible with CloudFlare.


A website has SSL. Is CloudFlare Compatible?

  • If a website has SSL, the site can use CloudFlare, however there is an extra step. If the SSL is on its own sub-domain (i.e. SSL), then ensure that this sub-domain is marked with a gray cloud. If the SSL is on www, then the user has to upgrade to a paid service (either Basic or Pro) and follow the directions outlined here.


Will CloudFlare accelerate and protect a root domain (i.e.

  • CloudFlare can only accelerate and protect CNAMES. Since root domains are an A record, we recommend that a website forwards its traffic to ‘www’ through their .htaccess file.
  • If the user does not forward the traffic, then any traffic to will be accelerated and protected by CloudFlare (and shown in the statistics) and any traffic to will not be served by CloudFlare.


Are there sub-domains that shouldn't be enabled with CloudFlare?

  • Sub-domains on CloudFlare are marked with an orange cloud. Sub-domains not on CloudFlare are marked with a gray cloud.
  • The CloudFlare network can only proxy web traffic over port 80 and 443. The following sub-domains should be marked with a gray cloud to prevent performance issues:
    • cpanel
    • direct
    • ftp
    • mail and webmail
    • mysql
    • nameservers (NS1, NS2)
    • secure* (unless you enable CloudFlare SSL)
  •  View the full list of sub-domains here:


Can I enable CloudFlare on a wildcard (*) sub-domain?

  • No, for security reasons, CloudFlare does not proxy traffic to a wildcard sub-domain. You have to explicitly list the sub-domain as a CNAME in your DNS records to be able to activate CloudFlare.


Can I enable CloudFlare on my root domain (i.e. that is an A record?

  • CloudFlare can only accelerate and protect CNAMEs, not A records, which often includes the root domain. If traffic goes to a root domain and you want to accelerate and protect the traffic using CloudFlare, you can add a redirect to ‘www’ in your .htaccess file.
