I run a Jitsi instance on Linode. I used their push-button setup, then tweaked the security settings slightly. I keep it off and on a minimal instance except when it's time for a meeting, at which point I move it to a dedicated host for the duration of the meeting. I always check my TLS/SSL certificates and update the OS before the meeting, too. It has been okay, but not as reliable as Google Meet or Zoom. There's often someone having audio issues, typically on an iPad. Before I switched to a dedicated instance, those problems were worse. One of my regular meeting participants co-founded the FSF, so I'm using Jitsi so that we're using open-source software. I'm a big fan of Jitsi, but I want to be realistic about its reliability in my experience.
