By the end of the day he would plug back something and come out the "servers room" saying he fixed that and get everybody's praise. Even got him two raises in the span of 18 months.
That's how crazy it is.
I know a variation of this sort of story, where a good sysadmin/DevOps team was halved and then the problems started. The company didn't have those issues exactly because they had a good surplus of eyes to handle everything.
They realized only later the mistake.
