IMO the best tracking site is the Johns Hopkins site https://gisanddata.maps.arcgis.com/apps/opsdashboard/index.html#/bda7594740fd40299423467b48e9ecf6. It’s having issues this AM, either down or slammed, it won’t completely load.

They are good, but it seems there was some infighting going on, probably students, over how to label countries and assign sovereignty. That was really messing with their numbers and databases yesterday. Looks like someone has taken away their access and the adults are in charge again, but now reporting is very slow. Hasn't updated in about 7 hours.
