Psiphon Usage Surges as Brazil Blocks WhatsApp

At 9PM ET on December 16th WhatsApp was blocked in Brazil. The ban came after a judge ordered that the messenger app be blocked for 48 hours when the company refused to hand over private user information related to a criminal case. For months, Brazilian telecommunications companies have been attempting to shut down WhatsApp because it provides free messaging and voice services. WhatsApp is the most popular messenger service in Brazil and telecoms blame it for luring millions away from paid cell phone use.

Internet users in Brazil reacted strongly to the ban, criticizing the decision to block WhatsApp widely on social media. Millions turned to alternate messenger services and shared circumvention techniques over social media. Psiphon was praised by people in Brazil for being free, open source, and able to keep them connected throughout the blocking event. Psiphon’s surge capacity was able to cope with the increased demand, with peak data use of more than 8x that of a normal day. Psiphon's unique users in Brazil went from 54,000 on December 16 to 946,000 on December 17.

Less than a day after the block was put in place, a second judge overturned the lower court’s decision and WhatsApp was unblocked. He stated that “it does not seem reasonable that millions of users be affected” because WhatsApp refused to disclose user information. While the surge use of Psiphon settled quickly, more than twice the expected amount of data was being served hours after the block was lifted.

Update: In May 2016 Brazil blocked WhatsApp again, and again users turned to Psiphon.

Why You Don't Need Google's Domain Fronting

Google’s removal of domain fronting emphasizes the need for solutions like Psiphon. Google has confirmed that they will block domain fronting across Google domains and App Engine. For many apps and publishers, this represents a step backwards in the fight for internet freedom. While Psiphon has never relied on this Google service, many app developers continued to depend on the practice as a convenient and straightforward means of circumventing state-level censorship, despite the long-running speculation that Google would close this loophole (eg. Will Scott’s blog post in 2017). While the announcement has been met with criticism from internet activists and service providers alike, Google has defended their decision, saying “ domain fronting has never been a supported feature ”. Domain fronting has been a popular means of censorship circumvention for several years, being embraced by popular apps like Signal, who publicly adopted the practice in 2016 . While using Google domain
