http traffic hangs with Big Sur

Occasionally, requesting a page with Safari will hang for 60 seconds or more and then load the page. If the hang is in process, email, zoom, ssh etc all work, but opening a page with Chrome or Firefox all are blocked while Safari is blocked and then load when Safari loads. Could not find any reference to a similar phenomenon through a google search. Anyone else see the same phenomenon?

MacBook Pro, 2019 model, Big Sur 11.6
