That's the problem you have. Defining "urgent". Logging activity gives you a sense of the quantity of work carried out after hours, but not the quality. An example we might have: our guys are working on a multi-million dollar deal and the client e-mails them from New York in the late afternoon. The client doesn't care that it is midnight where we are in the UK, he expects an immediate answer. That one e-mail is more important than the thousand e-mails we received during the day. In financial terms, it could represent 20% of our revenue. So 0.0001% of IT activity represent 20% of revenue. You can't analyse that. You can only trust that if your guys say they need 24/7/365 access, they do. And that is why I'm trying quantify who and when people are working while not in the office. Because as @Breffni-Potter said (and is true) the system will have to come down at some point, it might as well be planned, rather than unplanned.
