IT tries to be proactive at first, but being proactive usually costs money, so it's often ignored. And then a failure happens as a result of ignoring that issue and then the tech people get yelled at.

Reminds me of a line I heard once, can't remember where but it was definitely in the very context you mention here, it goes: "When people realize they can't reliably work with you, they start looking for ways to work around you"
