How stable is Centova Cast?
How stable or reliable are streams hosted by Centova Cast?
Centova Cast is simply a control panel for SHOUTcast or IceCast; it does not actually serve your radio stations itself.
The reliability, stability and uptime of your actual streams depends entirely on the reliability and stability of the streaming server software you're using with Centova Cast -- either SHOUTcast or IceCast.
Both are very well-tested, tried, and proven solutions that have been successfully deployed in countless small- to large-scale production environments. They are essentially the industry standard in online radio broadcasting, so you may rest assured that you are using the best and most reliable technology available to host your streams.
In the unlikely event that a SHOUTcast or IceCast process does crash, Centova Cast will automatically notice the outage and restart the stream within a matter of minutes (the exact response time depends on your cron job configuration).
In short, using Centova Cast in conjunction with SHOUTcast or IceCast should provide a very stable, reliable hosting experience for your streams.
