I know I can say I'm having downtime. How would you say it about a computer (system). It has/ it's on downtime every night from 2 till 5?

Yes. "The system will undergo scheduled downtime every day from 2AM to 5AM." is just fine. This is, of course, the opposite of uptime. If it is unplanned downtime, usually outage or network outage is used instead.

I can't say it will have.... or it will be on... ? – Dunno Aug 15 '13 at 14:34
Of course you can! The former (the system will have...) sounds better. I only wrote it the way I've seen it written in most announcements. – Amory Aug 15 '13 at 14:38
I was just trying to see if it on and have work – Dunno Aug 15 '13 at 15:37

System downtime is from two to five every night is short and sweet.

I like the sound of this:

The system will be experiencing downtime every night from 2 to 5 for [maintenance, repair, etc.].
