It looks like the latest Jetpack 2.0.2 setup for connecting to wordpress is failing. This is a connection established between the Jetpack code running on the machine hosting wordpress.org, and the jetpack.wordpress.com/jetpack.
The message is this, and it takes about 83 seconds to appear.
Jetpack could not contact WordPress.com: register_http_request_failed. This usually means something is incorrectly configured on your web host. SSL connection timeout
I've had support tix in to both wordpress.com and to my hosting provider (fatcow.com as it happens), and they can't figure it out.
It's possible things have been troublesome for a long time. When I deactivated Jetpack, my wordpress installation's admin performance shot way WAY up.
