I think it's just you, I clicked around the board a little and it was all responsive, my last page at the bottom said:
"Page created in 0.148 seconds with 27 queries."
Although particularly with the Covid board try minimizing the dashboard box. That can take some CPU/load time.
I had a similar problem a few weeks ago (not just with Covid - with all of scoop) and the other mods assured me that it was...just me. There may be some data center or switch between you and MUScoop that is acting finicky. Give it a couple days and it'll probably get better.
