As of 7/29/22 11:00am CDC site won't load with Firefox. It will load with Safari. Turning off Enhanced Tracking makes no difference. I'm current with all my updates. I'm Apple Monterey 12.4. CDC website worked fine a day or two prior.

Could you try my suggestion there: if you are getting a "Server Not Found" error, one possibility reason is that the DNS lookup -- the step where your browser tries to find the numeric address for the site -- failed. Could you try changing your DNS setting using the steps in the following article: Firefox DNS-over-HTTPS. Does having DNS over HTTPS either ON or OFF make any difference?
