| Sean, | | Why would they use this feature for that purpose? To fake a router | crash in order to load new software? Interesting way of "breaking the | rules." | | Chris Well, despite many strangenesses in my former company, operations never actually imposed a maintenance window along the lines of a competitor's "only Thursdays between midnight and four a.m. local time" which straitjacketed the people who were trying to build a network that would cope with the kind of growth it was undergoing at the time. So, one possibility was to wait for things to explode and then change the broken procedures, and the other possibility was load up new code in all routers in advance of the next maintenance window, and then if it became necessary, tactically crash ones that started suffering the worst problems. I don't think I ever actually used the knob, but I know at least two people who did. Sean.
