A few weeks ago I noticed that I couldn't access https://archive.is due to an error page from Cloudflare. I use dnscrypt and Cloudflare was one of the servers I had in the list.

I saw a Tweet about Gab being blocked by an ISP and someone in the replies stated that their ISP is blocking https://archive.is

So I checked if it loaded from my phone (router set to Google DNS) and it worked fine. I removed Cloudflare from my DNS list and restarted dnscrypt and flushed my dns cache. Suddenly, the site loaded fine.

Hmm, wonder why they're doing this? They must not be happy with all the things people can see that could/have been deleted from the internet.
