It’s funny how you can work with something for years, but miss a small detail. This week I learnt about Skew Time for VRRP. The reason for it is completely obvious once you think about it, but for some reason the detail had escaped me for all these years.

They’re worried about automation run amok. They think it’s safer to have a human typing in commands. But you know better. Humans have a place.
