I don't disagree with any attempts to request (or demand if you feel it necessary) additional compensation (perks, pay or paid time off). However, if you were hired to manage a data center with the intent to maintain uptime, that should already be factored into your compensation package. So saying people should "demand" more may, in some situations, seem like a slap in the face to your employer.

For instance, when I went home for Christmas there was a blizzard. A friend of the family worked for the city and had to clear the roads Christmas Eve and Christmas day. It's unfortunate because he didn't get to spend time with his family those two days. At the same time, that's his job. If he didn't want to do that or didn't want to do it for the amount he is paid, then he wouldn't have accepted job.

There are a lot of people that need to be more accountable for their duties and actions. If you agreed to the terms of employment, then hold up your end of the deal. If you feel it is necessary or time to renegotiate, do so.
