We monitor hosts for uptime and webspeed and we going to split our uptime metric into a Uptime During Peak and Uptime During Offpeak to avoid penalizing hosts that have scheduled maintenance during Offpeak hours. I'd appreciate some feedback on the hours of the day that each of you would consider "peak". For example, you could say that from 9:00a-6:00p CST is peak and every other hour is less critical. Or, you could say that hosts should only do maintenance from 1:00a-4:00a CST and everything else should be considered peak.

Opinions?
