Are these terms one of the same thing? I have a feeling that I might have to fix something if my client's server status is supposed to say "Offline" rather than the one I have now "Unavailable". If it's supposed to say Offline, my client might be broken.

Can anyone shed light on this question?

Other than linking me to the post Udyr states that the server is currently offline.

bump. My friends' status says "offline" so I'm not sure if mine's working.

Mine says unavailable. Working as intended.

Server is down atm for patching. Read the Top Sticky.
