VPN, Tor Use Increases in Iran After Internet 'Curfews'
Iran's government is trying to limit internet access, reports CNBC — while Iranians are trying a variety of technologies to bypass the blocks: Outages first started hitting Iran's telecommunications networks on September 19, according to data from internet monitoring companies Cloudflare and NetBlocks, and have been ongoing for the last two and a half weeks. Internet monitoring groups and digital rights activists say they're seeing "curfew-style" network disruptions every day, with access being throttled from around 4 p.m. local time until well into the night. Tehran blocked access to WhatsApp and Instagram, two of the last remaining uncensored social media services in Iran. Twitter, Facebook, YouTube and several other platforms have been banned for years. As a result, Iranians have flocked to VPNs, services that encrypt and reroute their traffic to a remote server elsewhere in the world to conceal their online activity. This has allowed them to restore connections to restricted websites and apps. On September 22, a day after WhatsApp and Instagram were banned, demand for VPN services skyrocketed 2,164% compared to the 28 days prior, according to figures from Top10VPN, a VPN reviews and research site. By September 26, demand peaked at 3,082% above average, and it has continued to remain high since, at 1,991% above normal levels, Top10VPN said.... Mahsa Alimardani, a researcher at free speech campaign group Article 19, said a contact she's been communicating with in Iran showed his network failing to connect to Google, despite having installed a VPN. "This is new refined deep packet inspection technology that they've developed to make the network extremely unreliable," she said. Such technology allows internet service providers and governments to monitor and block data on a network. Authorities are being much more aggressive in seeking to thwart new VPN connections, she added.... VPNs aren't the only techniques citizens can use to circumvent internet censorship. Volunteers are setting up so-called Snowflake proxy servers, or "proxies," on their browsers to allow Iranians access to Tor — software that routes traffic through a "relay" network around the world to obfuscate their activity.
