Internet
A stable internet connection is definitely necessary to run a successful live stream, but stable internet connection can be quite precarious even at the best of times. There can always be issues with internet connection, and on some level you have to accept that things may not work out one day. You should never strive for absolute perfection, especially when dealing with something as inconsistent as the internet. Still, there are some things to keep in mind. Everything that involves internet connection runs through a single chain of bandwidth, so don’t overwhelm that bandwidth. Restart your connection often, and use an Ethernet cable if you are not close to a router. Also, if you have access to multiple studios, they can be relied on as a back-up plan if your connection fails.
