Earlier quoted context omitted.
The President said it would be up on Sunday.
Here's the transcript from the press conference: https://www.rev.com/transcript-editor/shared/CmrNxLAP9wohLWA... I searched for "Sunday" there, and they only mention they'll be able to provide details of when the testing website will be available by Sunday evening. They didn't say the website will go live Sunday.
>> Mike Pence: For Americans looking on, by this Sunday evening, we'll be able to give specific guidance on when the website will be available
If anything it was the FDA approval of Roche's automated testing ability that was going to happen by Sunday, which was announced today (Saturday) with a 24 hour window [1], and is only one piece of the puzzle. We don't even have a brand name or domain for the "Google site" yet. The only domain he mentioned http://coronavirus.gov directs to a CDC content site, so it will probably just be via Verily, which only announced a limited SF roll-out so far.
The closest thing he gave to a direct response to the website question was a paper was being released after the press conference which outlines their plans. Not sure on the status of that. The Reuters article was last updated 17hrs ago yesterday so it might just be highlighting the press interview, not the paper.
