When I did this years ago I found 5 was really a minimum so that I could cover weekends and then had extra coverage as needed during the week. I did find it was good to swap out the graveyard shift every 6 months or so. -----Original Message----- From: harbor235 Sent: Friday, April 15, 2011 9:14 AM To: NANOG list Subject: 365x24x7 If I were going to provide a 365x24x7 NOC, how many teams of personnel do I need to fully cover operations? I assume minimally you need 3 teams to cover the required 24 hr coverage, but there is off time and schedule rotation? thoughts, experience? Mike
