When accessing websites using that use Cloudflare services, I'm getting "Verify that you're human" checks on many of them from my IP address (Google fiber). But when using a different ISP with a different IP address (ATT Fiber), I don't get the same checks.
Some of the examples of sites where Im experiencing this issue:
cloudflare.com
isbgpsafeyet.com
plex.tv
w3.org
namecheap.com
This problem seems to be isolated to Cloudflare, as my ISP claims no responsibility.
