Google Encrypted Search Moved to New Hostname to Address Concerns from Schools

Presumably schools whitelisted specific sites to allow https, and google was one of them, until it became a problem.
*Dr Evil pinky smile*It's not possible to do that. The firewall has no idea what's being communicated because it's encrypted!
So I don't really understand what they did here.
But the search suggestions use https://clients1.google.com/ and google should let schools know that block that as well. (Or maybe schools block all https except known good ones?)
We’re working hard to address this issue as quickly as possible and in a few weeks we will move encrypted search to a new hostname – so schools can limit access to SSL search without disrupting other Google services, like Google Apps for Education.
Did it return a 200 to you for https://google.com/?
