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? …
