I have not been able to use the site today. Everything is freezing up. I am logged in as usual etc

I know to do that from previous experience. So that is always my first step. It suddenly stopped last evening. No idea.  So it was only me then is a clue.

Very strange. We are not seeing this behavior.

Is it still happening today?
If so, can you let us know what browser you are using?

Maybe clearing your browser cache might solve the issue?
