I have a question about servers

Hi. I’m new to VATSIM and have a question about how the servers work. When you connect to a server, do you only see traffic and controllers connected to that server or do you see traffic and controllers from all servers?

I’m just wondering because otherwise I would use different servers depending on where I’m flying to get the most controllers in my flight region.

All servers are interconnected, doesn’t matter which one you use. In fact, the server list currently only has one entry in it, called AUTOMATIC, which will automatically connect you to the best server, usually the closest server to you, which has open slots.
