The nature of the internet means that websites can be here today and altered or gone tomorrow. This has given rise to the development of archiving services, and free online archivers such as’s Wayback machine and’s webpage capture. (also known as or quickly takes a current snapshot of any website for access in the future, and we use it extensively for backing-up and preserving sources and references.

It was brought to our attention recently that all of the hundreds of links on our site are inactive, with Chrome browser giving the error:
This site can’t be reached’s server IP address could not be found.
Try running Windows Network Diagnostics.

And Firefox returns “Hmm. We’re having trouble finding that site. We can’t connect to the server at”:

Hmm. We’re having trouble finding that site. We can’t connect to the server at If that address is correct, here are three other things you can try: Try again later. Check your network connection. If you are connected but behind a firewall, check that Firefox has permission to access the Web.

Firefox’s error

Upon further investigation it became apparent that this error only occurs when using Cloudflare’s free consumer DNS service, and links are otherwise working fine for everyone else.

This has been picked up on reddit, where users speculate that it could either be a technical problem between Cloudflare and, or possible censoring by Cloudflare.

Either way, anyone using Cloudflare’s DNS service can not access any links such as this archived wikipedia page for the concept of Chakras.

Sadly this is outside of our control, but there are some workarounds for accessing links while using Cloudflare’s DNS service:

Use Tor Browser

The Onion Router (Tor for short) is a free browser bundle and internet networking protocol designed to anonymise the data relayed across it, based on Mozilla Firefox. can be accessed without restriction at via the Tor browser, or accessed directly via their Tor site at archivecaslytosk.onion (only works on Tor browser).
If using the .onion address, any link – for example – can be accessed by placing the suffix onto the onion address, such as archivecaslytosk.onion/9qmQm

Use google translate

Use google translate to access

Google’s translate service has the advantage of acting like a proxy, so can be accessed when the URL is entered there, just select translate from something like “Arabic” to “English” (because google will not display the site from English to English).
For example, this link displays fine for anyone using DNS.

Use an online proxy

Use a proxy to access

Searching for “online proxy” on your favourite search engine returns many online proxies that enable links to be viewed using DNS.

The bug or censorship preventing users of Cloudflare’s DNS service accessing has been present for several months now, and it will be interesting to see if the issue is resolved, or whether more and more websites fall victim.
If you prefer to not use Cloudflare’s DNS service, you could revert back to your ISP’s DNS service, or use alternative free ones such as Google’s DNS service, or consider using a paid DNS service.

We are going to continue using for preserving sources and references, and will refer anyone with difficulty accessing while using Cloudflare’s DNS to the workarounds given in this article.
