Why was nobody flying today? (Sun 4/3)

I was checking the webcam page all day. Two gliders set up and disappeared sometime before noon then nothing else. The wind showed mostly W from 16-24.
What gives? Usually conditions like that on a sunny Sunday draw two dozen gliders at least. Did the site get shut down and I somehow missed the notice?
