It seems like TIME or MCMC is blocking maxcdn.bootstrapcdn.com.
It's a CDN used by a lot of websites to provide CSS and Javascript. Blocking it has resulted in many websites not loading and broken.

maxcdn.bootstrapcdn.com is being redirected to mcmc.time.net.my


Can anyone confirm that it's being blocked that's using TIME or other providers? I am only using TIME so I can't test it on other providers.
I tested it on my phone, laptop and computer with default DNS and it's all being redirected to mcmc.

Normally i don't realize this as I'm normally using a 3rd party DNS server

Yup, TM DNS server (1.9.1.9) also same.

I'm sure those online gambling sites have a FAQ on how to bypass ISP DNS block.

Issue like this, website seriously need an E-SNI/ECH and DoH as default! encrypt domain name making ISP Layer 7 Firewall useless, also no need VPN!

In before Cloudflare and Googleapis gets blocked for being in use by almost every "illegal" website. notworthy.gif

Circumventing blocks is never, ever the solution. Blame lies with the authorities for letting stupid mistakes like this get rubberstamped and it falls on the lawmakers to ensure the vetting procedure gets a more thorough treatment. (Email your MP!)

Fun fact, they did accidentally block some of Cloudflare's AnyCast IPs once

Using DNS over HTTPS (DoH) and TLS 1.3 (ECH) can bypass
DoH to protect DNS IP Query, meanwhile TLS 1.3 protect SNI

in wireshark, TLS host is encrypted when using version 1.3

now Web Server need to support and enable TLS 1.3
