If you use Cloudflare's DNS (1.1.1.1), then the popular web archive archive.today (and the related sites archive.ph, archive.is, archive.li, archive.vn, archive.md, and archive.fo) will either fail to resolve, or show an infinite CAPTCHA loop. If it does resolve when you're on Cloudflare's DNS, you may have the domain locally cached.
Fix this problem by:
- Configuring
dnsmasq
on your local DNS server to use an alternate DNS server for archive.today (see comment from @joshenders below), or - Connecting to a VPN before connecting to archive.today (only works if the VPN uses different DNS servers), or
