China appears to have upgraded its Great Firewall, the instrument of pervasive real-time censorship it uses to ensure that ideas its government doesn't like don't reach China's citizens.

Great Firewall Report, an organization that monitors and reports on China's censorship efforts, has this week posted a pair of assessments indicating a crackdown on TLS encryption-based tools used to evade the Firewall.

Interestingly, domain names used with these tools are not added to the Great Firewall's DNS or SNI blacklists, and blocking seems to be automatic and dynamic.

Earlier in the week, Great Firewall Report also posted analysis asserting China has barred google.com and all of its subdomains.

Which is an odd thing to say given that China started blocking Google in 2010 and Greatfire.org, another service that monitors China's internet censorship, says Google and its online services, including YouTube and Google.com, are 100 percent blocked in China, and have been blocked for ages.

Great Firewall Report believes 1,147 google.com domains are now blocked in China - even though they were probably blocked already in some way or another.
