Online testing data indicates that at least 3 international LGBT related sites are on the Malaysian Communications and Multimedia Commission (MCMC) block list. Local LGBT community websites however are currently freely accessible to Malaysians.

Malaysians trying to access the blocked sites Planet Romeo, Gay Star news and Utopia Asia on local ISPs will be redirected to the IP address (175.139.142.25) of MCMC server that serves the the official notice. This notice page may not load up, and some users on different ISPs may encounter a connection or 404 page not found error.

DNS Hijacking is a method in which ISPs will replace the original target address of a web server to a different one.  

We are doing continuous monitoring on the state of Malaysian online censorship, using Open Observatory for Network Interference (OONI) probes and global and country specific Citizen Lab test-lists of sites related to but not limited to freedom of expression, human rights, news media, sex education, religion and LGBT.

A list of all currently detected censored or blocked Malaysian websites is published at data.sinarproject.org
