Network Down!

I have had Comcast cable for network connectivity for the last year or so. Absolutely no problems whatsoever, it has been very reliable. I know others have network problems quite frequently, so I am very happy about our network situation. However, my network stopped working a couple of days ago. I think just about everything in our house uses our network except our Electric Blankets. Talk about being hampered, felt like I was in the Stone Age. Had to use WiFi Hotspot on my iPhone 8. The network was repaired the next day, all is well. We definitely take this stuff for granted.
