If they did, I didn't hear it. But my timeline guess is that if they announced it on Saturday, they already had the servers and network nodes needed (hardware) in house and connected by Saturday. Software and security installed and testing on Sunday, maybe Monday. Network/internet testing on Monday, Tuesday. Hopefully they don't run into any problems but also don't rush into it so they can go live by Wednesday. And that's with IT working 24/7.
Trump said the Democrats blaming him for the virus was a hoax, not the virus itself. The Democrats politicized the virus first during one of their debates. The hate some have for the President is crazy, that side says they are the peaceful side but all I see is hate and a lot of complaining.
