I think some people confuse "service interuption" vs "network failure". The "Internet is down!" is a generic term for "things aren’t working". In the case of server/streamer/player, music files sitting on the server are not dependent on ISP functionality. As long as your network is healthy everything in your intranet should be just fine. No need to bring out the ukulele.
If things are not working and you are musically compromised, you can introduce a new topic to the group for discussion like: "Should birthdays be celebrated ON your birthday, and not another day that’s more convenient?" It could be quite engaging?
