Takes me back to the first broken mess of an environment I worked in. Change freezes were a day of life and lasted and, magically, nothing would break during that time.

Now, those change freezes even extended to preventative maintenance, one of the dual PSUs in a core switch went bad and we couldn't get an exception to replace it... for 6 months. We got an exception when the second one went down and we had to move a few connections to its still alive mate.
