Hello PK,

For me, backend uptime is mixed. I've had some backends last for hours, and 
some backends that last for only 30 minutes before needing to be stopped 
and moved to another server. It's pretty much the luck of the draw - what 
server that the scheduler picks to run your app, and what other 
applications are running concurrently on that same server.
