Yeah, my idea was that the placeholder looks like

"OFFLINE:{whitespace*}{message}{whitespace*}"

where message can be anything you want.

Examples:

OFFLINE: Our business times are 08:00 to 18:00 CEST

OFFLINE: Please come back later. My server is currently down! - xq

OFFLINE: Sorry. Looks like i have a power outage again. Should be back 
up in 20 minutes!

I don't think a more "technical" thing is a good idea here, as the 
reasons for "server unreachable" are manifold
