Suddenly my network is down
I don't know. You didn't really give much to work on. This is like you showing up to a hardware store and say, "I need stuff".
check if this helps
Not even going for the doctor analogy?
Nah. If I use the doctor analogy, one could assume we actually are trained to do this (which we are not, doctor can represent the dev). In a hardware store setting, the person in there aren't necessary a carpenter, plumber, or electrician. They can merely a handyman (the community), just there to help people out with stuff.
I think reboot will resolve the issue if not then there might be some issue with the network in your area. Otherwise, this guide might help you out.
