Hi Constant, out streaming server zap stream had some issues two weeks back and we've made progress since then to resolve it.
First of all I hear Kieran invested quite heavily in new infra, and ZS appears more stable since.
Then also for Shosho we made it so you can use any server you like, not just ZS. So if you want to stream to CloudFlare or self-host an SRS or whatever you want to do, you can now add and use your own server of your own choosing.
There's a user here who sets up their own API Video instance.
If that's hard, just keep using the default as ZS is back online and stable.
I'm always here and looking for feedback so if you get stuck please message me or raise an issue on GH.
