The event I stated in my first email was an example, not an actual incident.I think from the 30+ emails I have received I have had 2 responses that said I should start my SLA credits and outage minutes from the beginning of the window and the rest that feel the outage minutes start ticking when the planned outage was over...
Regarding Change Management procedures, we do have had deadlines for backing out, verification, etc etc. But you are right...

Heya, I disagree as this entire event wasn't a planned outage. The "planned" part was what you intended to do and, if its anything like the maintenance reports that I send and receive, you typically state how long you expect the impactwill be and that it will take place within your maintenance window. I'd arguethat you should start the clock ticking when the outage first happened and then take off from that whatever you annouced as the impact duration.For example, if you said that the impact would be a ten-minute outage sometimeduring your window from 2am to 5am and your outage started at 2am, I'd count this as an unplanned outage starting from 2:10am. That's just my $0.02... On another note, you had a 3 hour window and a 6 hour outage. It sounds likesomeone didn't seriously consider the "back out" part of your change managementplanning. You really should have that as part of your process and have a hard deadline within the window after which you revert the network to its previous state. Eric :)
