I got called out in email, I think reasonably appropriately, for using the term “off-times” when referring to choosing a better time to do our sprintly upgrades. In a 24×7 continuous service world, there really is no such thing as a “good” time to have a problem.
Today we did our last deployment of 2013 (Sprint 57). You can read about it here: http://visualstudio.com/en-us/news/2013-dec-11-vso
Our next deployment would normally fall very close to the Christmas holiday and to avoid that, we’ll be skipping the Sprint 58 deployment and just rolling all of that work into the Sprint 59 deployment in mid January.
We are doing a pretty quick turn of the crank on VS 2013 Update 1. Originally we were thinking our first Update would take a little longer but for a variety of reasons (most prominently the feedback about VS supporting versions of IE before IE 10),
Ed Glas, Bill Barnett and Jiange Sun published a detailed write up of their experiences load testing VSOnline/TFS. It’s a good read because they go into a lot of the reasons for the things they do and also talk about things they’ve tried that didn’t work.
