You can only do this for so long though, when two or three problems come in simultaneously it can cause issues as you drop something halfway through when something more important comes in. I once executed an SQL update query without a where clause under this kind of pressure, and ended up working until the next morning to recover, only to start again at 6AM. I have even had land-line calls at 2AM to bypass my mobile restrictions. The rewards are great, but don't let anyone tell you it is always easy.
My current system is 16 years old now and I know all the ins and outs so it has been pretty easy to keep on top of things the last several years, however I am glad the replacement system is nearly written and it will be somebody else problem in 2026.
