There should be nothing new. Google services are blocked for several years. But not every service is blocked in the same way.
Google+ and Docs is wholly blocked a long time ago. Google.com is blocked intermittently. Gmail and Maps are usually OK, but not very fluent these several days.
GFW is a mysterious monolithic and complex system. No outsider knows the rules and mechanisms.
I agree. I just want to add that I think they have a "degrade" mode designed more to be annoying than to block access. I know people here in Shanghai who hate Google products because they're so "slow", "unreliable", etc. Of course, they're perfect through a VPN.
