I can indeed help with this. The first step is to create the Experimenter ticket that Tim made. Lets get all of the needed sign offs there. Specifically, we'll need signoff from Relman (Julien you can do that), and QA.
Looking over the details that Tim put in Experimenter, this sounds like an ideal use of Normandy's Preference Rollout feature. We can ramp this up however fast is desired. Our normal schedule is weeks, but we could do it over a few hours if needed.
Wes, Sunah, heads up that we might be putting a large load on the Telemetry system soon, due to calls to
setExperimentActive. We have finished the rollout of the 1 hour skew feature, so I don't expect any issues will come up.
