Using Cloudflare as CDN for debian.org website



Dear debian.org webmasters,

CDN (Content Delivery Network) is a service that distribute website's content into different servers across the world. This way, when a visitor in Singapore (for example) visit a website which hosted in Europe, the website assets will be served from CDN server in Singapore or nearby instead.

The benefits of using CDN are (quoting from wpbeginner.com):

Cloudflare is one of leading CDN provider in the world. Beside providing CDN service, it have DDOS protection which can be handy regarding security.

Is debian.org website currently use CDN? Either answer, is Cloudflare CDN suitable for debian.org website?

One of interesting feature of Cloudflare is reCAPTCHA challenge every time visitor access website which have this feature enabled. Before a visitor can reach website, there will be reCAPTCHA challenge which visitor must answer in order to get access to website's web property. Usually, visitor must click "I'm not a robot" checkbox and must select squares which contain a particular object (in most cases related to road infrastructure in USA). In order prevent the challenge, Cloudflare says in the challenge page:

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.

If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.

Another way to prevent getting this page in the future is to use Privacy Pass browser extension

However, in the challenge page the visitor's IP address is also displayed. Is it OK for debian.org website to use reCAPTCHA challenge feature (which is available in Pro plan and higher) when using Cloudflare as CDN?

Regards, Bagas
