HKmap.live: Crowdsourced Protest Maps and Censorship in Hong Kong

What HKmap.live is

HKmap.live is a crowdsourced mapping platform that emerged during Hong Kong's 2019-2020 pro-democracy protests. The service allows users to annotate real-time information about police presence, roadblocks, protest activity, and public safety conditions across Hong Kong's districts. The platform operates without a formal corporate parent; it was developed by volunteer technologists and maintained through community contribution. User base expanded rapidly during peak protest periods, with daily active users numbering in the tens of thousands at peak usage. The service is technically simple—a map interface overlaid with user-submitted pins and text annotations—but functionally significant as a coordination and information-sharing tool.

Why it's censored

Hong Kong's government and mainland Chinese authorities have targeted HKmap.live as part of broader suppression of protest infrastructure. Under the National Security Law (NSL) implemented in June 2020, mainland China and Hong Kong's Department of Justice classified the service as facilitating illegal assembly and obstructing police operations. The law carries penalties of up to life imprisonment for "secession" and "subversion" charges, and authorities have explicitly cited information-sharing platforms as enforcement targets.

The Hong Kong Police Force, via its Cyber Security and Technology Crime Bureau, has publicly stated that HKmap.live violates the Computer Misuse Ordinance by enabling unauthorized access to police operational data. This framing is technically dubious—the service relies solely on user submissions, not system intrusion—but has provided legal justification for blocking and operator prosecution.

In mainland China, the Great Firewall maintains blanket censorship of the domain under political-sensitivity classifications. The service is categorized alongside Taiwan independence materials and Tiananmen Square documentation as content threatening "national security."

Technical blocking methods

In Hong Kong, blocking appears multi-layered. Primary ISPs including PCCW, HKT, and Now TV implement DNS-level filtering, where queries for hkmap.live resolve to null or ISP-controlled notice pages. IP-level blocking of the service's hosting infrastructure is also documented, though the service's distributed hosting model means blocking effectiveness fluctuates. SNI (Server Name Indication) filtering has been observed on some networks, targeting the TLS handshake itself.

In mainland China, the Great Firewall employs DPI (deep packet inspection) combined with IP filtering. Connections attempting to reach hkmap.live trigger connection resets; the infrastructure is blacklisted at the border gateway level.

User workarounds

VPN-aware users typically circumvent DNS blocking through VPN tunnels that route all traffic through external gateways, bypassing ISP DNS infrastructure entirely. This remains effective against DNS-level filtering but is less reliable against IP-level blocking in jurisdictions where the hosting provider itself is blacklisted.

Alternative DNS providers configured at the device level can bypass ISP filtering but not IP blocking. Tor Browser provides higher circumvention reliability but at significant speed cost for real-time mapping applications.

Alternatives

Google Maps and Apple Maps, while available in Hong Kong, are subject to political content restrictions in user-contributed layers. OpenStreetMap, community-maintained and decentralized, has seen increased use for protest documentation but lacks the real-time annotation features of HKmap.live. Telegram channels and encrypted messaging groups have partially replaced the mapping function for protest coordination, though these operate outside map interfaces.

Outlook

Restrictions on HKmap.live are tightening, not easing. As of 2024, blocking remains consistent across major Hong Kong ISPs. Government statements indicate intent to prosecute service operators, currently operating in exile. Mainland China shows no indication of relaxing filtering. The service's decentralized successor projects face similar targeting under NSL provisions. The technical blocking infrastructure is becoming more sophisticated and harder to circumvent through standard VPN approaches.
