Iranians suffered a widespread internet outage on Monday, the second disruption in 10 days to leave millions without access to email and social networks.
The latest outage blocked access to all encrypted international sites that operate on Secure Sockets Layer protocol, Reuters reported.
"Email, proxies, and all the secure channels that start with 'https' are not available," a Tehran-based technology expert told Reuters. "The situation regarding accessing these websites is even worse than last week because the VPNs are not working."
Many Iranians use proxy servers over Virtual Private Networks to circumvent government efforts to block access to foreign news sites and social networks such as Facebook and Twitter.
