UNKNOWN service state question

[Nicole Hähnel]

Hmm...
And why is UNKNOWN a hard state and not soft?
I would say, unknown is like critical and I need OK to know if 
everything works allright in a network.
So why should nagios wait for the next normal scheduled check if it is 
unknown if a service is OK?
