So what's the story with DTC upgrades these days? Stabilized?

After the back and forth a few weeks ago I'm still sitting on .682 trying to see what the landscape looks like for desktop central upgrades.

My instance reports the current version to upgrade to is 10.1.2119.9, although when I click on the link from the notification its actually showing 10.1.2119.10

Is it stable? I believe I saw it mentioned a bit back that people were see very slow upgrades, and some instances of a non functional dtc instance after the upgrade? 

edit: we always just abbreviate desktop central internally as dtc, quicker to type.
