'a server' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'intermission it's not good' is the wordplay.
'intermission' becomes 'break' (synonyms).
'it's not good' becomes 'point' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'break'+'point'='BREAK POINT'

'for' is the link.
