KUALA LUMPUR: The Malaysian Communications and Multimedia Commission (MCMC) has instructed Internet Service Providers (ISPs) to redirect Domain Name Service (DNS) traffic that uses third-party DNS servers back to their own DNS servers.

No further information at all. I suppose they must have blocked DoH as well?

It makes me think of the previous discussion in Indonesia: https://github.com/net4people/bbs/issues/316#issuecomment-1864401572.

So basically the current system is, every ISP must redirect port 53 to their own server, their own server must be synchronized to Kominfo's RPZ server so it can update the blocking efficiently.

And there did eventually appear DoH/DoT blocking in Indonesia, in December 2023: #319.

DoH & DoT blockings are tested to already be in place, though not consistently implemented among different ISPs within Malaysia.

Legacy DNS on port 53 are also tested to still be working for lesser known servers, so it is looking to be server-specific DNS redirection, nothing remotely resembling DPI or GFW in terms of sophistication.
