Before 30 June 2020 Local ISP shutdown – March 1995 In March 1995,
Royal Hong Kong Police raided all but one of the pioneering local ISP offering dialup service, confiscated their servers and records and shut them down for a week, blocking the access of 5000 to 8000 of Hong Kong's early Internet adopters. The raids were thought to be instigated by Supernet, the one ISP not shut down, and coordinated by the Office of Telecommunications Authority (OFTA) working with the Commercial Crime Bureau (CCB) on the premise that the ISPs were operating without applying for a then-obscure Public Non-Exclusive Telecommunications Service (PNETS) Licence. The companies shut down were Hong Kong Internet & Gateway Services (HKIGS) hk.net, Hong Kong Link InfoLink Ilink, Internet Online Hong Kong, Cybernet, Internet Connections, and Asia Online.
Edison Chen photo scandal – January 2008 In January and February 2008, the
Hong Kong Police Force arrested ten people who were accused of obtaining, uploading, or distributing pornographic images after
Emperor Entertainment Group (EEG), a multi-billion entertainment company, filed a complaint about the availability of the photos on the Internet. The images in question, which were explicit in nature, were of the Hong Kong actor
Edison Chen engaging in sex acts with various women, several of whom were local actresses. The scandal shook the Hong Kong entertainment industry and received high-profile media attention locally and around the world. The police met with more than 200 people responsible for major Hong Kong websites and BBS communities to urge them to delete the pictures "as they have the responsibility to stop crimes". Related discussion threads were progressively deleted. The police ordered several locally registered websites and BBS management firms to submit information about their clients, and had retrieved the IP addresses of more than 30 Internet users who allegedly posted photographs. The police crackdown raised questions over violations of the privacy and free speech rights of Internet users and the selective application of the law.
After 30 June 2020 Article 43 of the Hong Kong national security law, which came into force on 30 June 2020, authorized the police to order "a person who published information or the relevant service provider to delete the information or provide assistance." (see
Hong Kong national security law) Since then, the Hong Kong government has been blocking several anti-government or politically sensitive sites. (see below) Hong Kong ISPs generally block websites in their home broadband and mobile data networks, and most public Wi-Fi networks are also affected. However, most providers do not implement blocking arrangements when offering enterprise networks.

Hong Kong police officers and

Several local news reporters confirmed that the site could not be accessed within the city. The police declined to comment on the blockage. However, in a statement, they said they "can require service providers to take restrictive actions against messages posted on digital platforms, which likely constitute the offense of endangering national security or incite a national security offense."
Hong Kong Broadband Network, one of the biggest mobile telecom companies in Hong Kong, said they have disabled access to the website in compliance with the requirement issued under the National Security Law on 13 January 2021.
