Do you support the Cloudflare service?

This page is showing a generic answer.
To see a more detailed answer customized for you, type your domain name here:

The third-party Cloudflare service offers features that, in some cases, can enhance the performance and security of websites. In particular, it can offer protection against some (but not all) types of denial of service attacks.

It can also make your site handle large bursts of traffic that would overwhelm any site hosted on a single server (no matter how fast that server is), because it spreads temporary cached copies of your pages on many servers all around the world.

You can use Cloudflare with a site that’s hosted on our servers — it should work properly. However, you must set up your “DNS Zone File” in the Cloudflare control panel a certain way. You can’t just use the default entries that Cloudflare automatically suggests: if you do so, they’ll “hard-code” the current IP address of your website into their records, which will stop working when the IP addresses eventually changes. We’ll repeat that again because it’s so important:

Never use an IP address in the Cloudflare DNS settings.

The instructions below do not include any IP addresses or “A records”. You should never enter an IP address at Cloudflare. Doing that will cause your site to eventually stop working because your IP address is not permanently “static”.
