Generally, there's two different ways we do throttling for releases. Most of the time we ship a release partly throttled (10% served), throttle it completely 48 hours later (at the request of RelMan through release-drivers and/or a bug), once some amount of users have it in their hands. In certain cases (for example, when our release day coincides with a Microsoft patch Tuesday), we ship a release fully throttled (0% of requests are served an update). | Generally, there's two different ways we do throttling for releases.

We're usually told explicity "please push release xxxx fully throttled" or "please push release xxxx partly throttled", but if you're unclear about whether a release should be throttled or not, ask on release-drivers prior making the updates live. If you're confused about anything else, ask another RelEng person. | We're usually told explicity "please push release xxxx fully throttled" or "please push release xxxx partly throttled", but if you're unclear about whether a release should be throttled or not, ask on release-drivers prior making the updates live.
