It sounds like the major ISP had a DNS resolution problem. It happens sometimes. The NOAA weather radio may use the internet to deliver the audio to the radio transmitter, originating in a studio somewhere else. If they have no backup means to deliver it, or if the main mode and the backup mode are both using the same internet, this would cause the radio station to go dark.

An example of this would be a cut fiber optic trunk in between major cities that otherwise are pretty isolated and have no other means to get to the internet. These often take hours to days to repair, depending on the complexity of the break. In my city, a backhoe operator accidentally cut a fiber trunk that my work uses, and it took us offline for 48 hours. That line has been in continuous operation without failure for over 10 years. Fortunately, I had put in a backup system that uses a completely different path, and we were able to cut over to the backup without any issue, or my company would have been down for 48 hours.

I have no explanation for the military aircraft, but the internet and NOAA weather radio problems you are describing are pretty mundane. I work in the biz.
