Hong Kong Protesters Flock to Off-Grid Messaging App

Hong Kong Protesters Flock to Off-Grid Messaging App


The New York Times 

Amid swelling pro-democracy demonstrations in Hong Kong, protesters are turning to FireChat, a new app that allows them to send messages without a cellular or Internet connection.
Set off against a fresh wave of censorship by Beijing to ensure that potentially destabilizing images of the protests do not enter the mainland, the app is a testament to how the protean development of technology constantly challenges tried forms of blocking information online.

Introduced in March, FireChat makes use of a cellphone’s radio and Bluetooth communications to create a network between phones close to one another — up to about 80 yards — without connecting to the Internet. If a cellular signal or wireless network is available, the app uses that.
In 24 hours starting Sunday afternoon, the app, which allows users to host public chat rooms, added 100,000 users in Hong Kong and peaked Sunday night at 33,000 simultaneous users.
The surge in users was due in part to rumors that spread over the weekend that the Hong Kong government might shut down the Internet, according to protesters, though it is unlikely officials would make such a move.

Nevertheless, Kyle Hui, 19, a student at the Hong Kong University of Science and Technology, said the app was proving useful because large crowds had overwhelmed the mobile infrastructure in parts of the city, rendering cell signals spotty.

“Protesters use it to, for example, announce what supplies are needed — goggles, surgical masks — or to announce protest tactics,” Mr. Hui said.

The Hong Kong protesters are not the first to make use of the technology. In March, just 10 days after FireChat was released, students participating in the Sunflower Movement in Taiwan downloaded the app en masse out of concerns about the Internet being cut, said Christophe Daligault, an executive with Open Garden, the San Francisco company that distributes the app.

The company also saw a jump in users in May, after the Iranian government blocked access to the photo-sharing app Instagram and the messaging app WhatsApp.

“When people find themselves in the situation where they think access to the Internet is going to be removed, they all download the app in big numbers,” Mr. Daligault said by telephone.

In Hong Kong, fears that the Internet might be blocked may have gained credence because Beijing has occasionally used the tactic, as it did in the western region of Xinjiang during riots in 2009.
Thus far in response to the Hong Kong protests, Beijing has heavily censored social media on the mainland, scrubbing references to the demonstrations from Sina Weibo, a popular microblogging service. Instagram has also been largely inaccessible in mainland China since Saturday, according to users and several Internet watchdogs, leading commentators to speculate that the government shut access to the app to staunch the flow of images of the protests. Instagram did not respond to a request for comment about the apparent blockages. Facebook, which owns Instagram, has been blocked in China since the riots in Xinjiang in 2009.

For now, FireChat has only a modest presence in mainland China, in part because potential users need Internet access to download the app and its site has been blocked, according to the company. Still, if the company were to take a new approach — for instance, work out a way for users to download and sign up offline — that could expose new vulnerabilities in China’s network of filters, known generally as the Great Firewall.

Even so, FireChat faces some of the same problems faced by all social media — such as the uncontrolled spread of rumors and overwhelming streams of data, Mr. Hui said.

“Sometimes I get more than a thousand messages in just an hour, so I simply can’t keep up,” he said.
“People keep posting the same message to grab others’ attention,” he added. “And I’m skeptical of many of the rumors that spread on the app, like saying that the People’s Liberation Army is sending in tanks and armored vehicles.”
