Where to Upload Maps Besides Steam Workshop?

[DirectKEK]

So I made a map and uploaded it to the Steam Workshop, but how can I upload to somewhere else so maybe another server can have it? I heard something about a site called ''Gamebanana" but otherwise have no idea where else to upload besides the workshop. Where could I do that so a server could play it? (Not actually gonna do that but would be nice to know)

Servers can run any map uploaded to the workshop, you don't need to upload it anywhere else.

Ask the server admin. They are in charge of any custom content for their server.
