I logged in to check if there was any change to my delivery estimate, and was shocked to see it saying that I reserved today, not on 3/31/2016 anymore. I thought maybe they lost my reservation info. But I logged out and back in again, then it showed the expected date. So it seems like the Mytesla site is being a bit flakey today with reservation info.
It did this more than once.
