Draftjs.org is blocked in India

[jeswinsimon]

Do you want to request a feature or report a bug?

Issue affecting the documentation site. Raising this here as there is no separate repo for the documentation site.

What is the current behavior?

Visiting drafts.org from India displays a blocked notice.

I am not facing any issue visiting draftjs.org here in india. it must be some temporary issue. @pk058 can you check it again.

I am also facing the same issue. Using VPN is the only way it seems.

👋🏽. I've been documenting this issue across multiple websites.

Here's why this is happening: https://github.com/captn3m0/hello-cloudflare/

Here's how to fix it (Only takes a minute): https://github.com/captn3m0/hello-cloudflare/#help-my-website-is-blocked

Here's a curl log that demonstrates the issue (note that this happens even over HTTPS, because the MITM happens between CloudFlare and GitHub Pages.

To everyone reporting that they don't see it blocked, since the site is hosted on Cloudflare, you need to hit one of the POPs (edge locations) that are peered with Airtel for the block to occur. The DEL POP is known to do this much more.

It is reproduced more reliably if you are on an Airtel Broadband/Mobile connection (and remember to disable all DoH/VPN etc).
