EDIT, for more clarity: Gmail spans lots of clusters ("Gmail's web interface runs in many locations”, https://gmail.googleblog.com/2009/09/more-on-todays-gmail-is...) and Google is an US-centric ("5%") company, so it's likely that the rollout has been timed to be complete or mostly complete during the day... US daytime, that is. It's barely 5AM on the East Coast.

Maybe someone could post the link that is behind "Try the new Gmail" - I assume it's just some URL parameter you need to add?

Clearly it's a staggered rollout thing that hasn't fully taken effect. (Which is stupid, when you do this kind of thing at scale you pick an exact time to go "live", add some code that enables the flag at some point after that exact moment in time, then do a rollout early enough that all the machines in the cluster are updated with that code by the time rolls around. And then everything "just updates all at once." Why do I suspect that Google from 2006-2009 would have made the effort to do that for this update, but that nowadays it would have been deemed as too difficult or whatever...)

I wonder what happened. Maybe enabling this _now_ was a last-minute decision? Weird.

I can't enroll with any of my personal or work accounts.
