Tried the COVID-19 map again. This time it loaded but is not configuring. So, we shall see....
Just tried again - loads with no data and asks for a sign in. Different from the first though. First time took me to a different page for sign-in. This time it was a small pop-up block which then directs you to the different sign-in page. So yeah they are metering the viewers likely due to bandwidth and have been making it pretty as the day goes on.
