Failure to connect

I teach online full-time.  On Monday, 9/10 at around 6 pm, there was a failure to connect.  Zoom buffered indefinitely.  My internet connection was fine because I was able to do searches in Google and on Edge.   I had to cancel the class.  I had been working on the laptop (hp intel core i7) all day.  I had even had a Zoom training that morning.  There is nothing wrong with the computer.  I had a Zoom training meeting this morning.

I would like to know if anyone else experienced an outage or glitch or whatever you want to call it, on Monday, 9/10 at around 6 pm.  What should I do to troubleshoot in the future?  How should I handle it?  Cancelling is really not a good way handle the situation. i am teachin about a following site
