Cuba is accused of having adopted China-made technology systems to control and block internet access, amid reports that messaging apps and Cubans' internet service are being blocked in the communist-ruled country after thousands of citizens took to the streets on Sunday to protest against a lack of freedoms and worsening economic conditions.
Thousands of Cuban citizens took to the streets in several cities spanning the communist Caribbean Island on Sunday, calling for greater freedoms and an end to the communist dictatorship. They also protested against ongoing food shortages and high food prices amid ongoing worsening economic conditions in the country made worse by the pandemic.
Alp Toker, director of Netblocks, a London-based internet monitoring firm, told The Associated Press that Facebook, WhatsApp, Instagram, and Telegram had been blocked. Twitter did not appear to be blocked but Toker said the regime could cut it off if it wants to.
Internet access has been limited and is expensive in Cuba. The communist regime announced in 2017 that it would gradually extend home internet services, and in 2019, homes and businesses were allowed private Wi-Fi networks. Cubans were also given full mobile internet access in December 2018 via state telecom company ETECSA—the only company that provides internet access.
Chinese technology has previously been implicated by various groups as being potentially used by the Cuban regime to facilitate its censorship.
"The server header of blocked sites, for example, pointed to Huawei equipment," the report stated. "While it is clear that Cuba is using Huawei’s access points, it remains unclear whether and to what extent the company is actually implementing internet censorship in the country."
The group also said it had found Chinese codes used for Wi-Fi access portals in Cuba, noting that the login portal of state-owned ETECSA contains in its source code "comments written in Chinese." The report stated that this "indicates that ETECSA likely hired Chinese developers to implement the portal."
It further notes that the server HTTP header contained "V2R2C00-IAE/1.0" which "appears to be associated to Huawei equipment called eSight," a network management system.
"The presence of the V2R2C00-IAE header in some 'Web Filtering' responses suggests the presence of a NIP product (Huawei Intrusion Detection System) that sits inline in the network," the report stated.
