I am retiring one of my systems that is using some energy for processes that don’t require a lot of system resources and one of the things it did was run my Icecast relays. I switched the Icecast relays to one of my virtual systems and will have a backup for them ready on another system.
Had you been connected to my Icecast relay you would have had a brief buffering like pause and been reconnected.
I just had to install from a repo on to one of my Centos 7 systems copy over my configured icecast.xml file from another system, change the ip.address/system names appropriately in the file then open my ports with firewalld, forward ports on router, then point to the new system in my Broadcasting software SAM and I was back up again. I did notice some brief disconnects but they came right back!
