The CTO was giving me and some others a quick datacenter tour. As we were exiting one floor, the new NOC mgr moved passed me and commented to his new boss that putting an uncovered big red button next to the door was just too inviting... and he proceeded to push it as he asked what it does. :-) All the lights went out, the large room went quiet. The CTO cursed and rushed out to figure out what to do next. The rest of us returned to the NOC... where the monkeys were still powered up and playing games, not even aware that anything had happened. Needless to say, things changed drastically shortly thereafter. -Jim P.
RE: PG&E on data centre cooling..
There's at least one datacenter in Seattle that when the customer "cards" in, lights up the floor to their cabinet Been a while since I've been in it, but I remember it "USED" to do that (fisher, internap I think?) Perhaps the infamous "unescorted customer EPO button-push incident of 2005" prompted them to knock that off? --chuck

The algorithm used in this report proposes aggregation only
when there is a precise match using the AS path, so as
to preserve traffic transit policies. Aggregation is also
proposed across non-advertised address space ('holes').
