As a web developer of 15+ years, I don't buy the" too much traffic and lagging" answer. The primary reason is, I filed a week ago and got my accepted message hours later and, when I check the site, the orange bar is there as it should be. But my sister who got her accepted message 22 days ago, orange bar is gone. It disappeared 2 days ago. We use the same laptop PC and the same browser.
I think the most likely reason for the disappearance is the fact that her return contains the EIC tax credit and, they aren't expected to be made available until after the 27th of February, 2020.
