Approximately 3 hrs ago we lost B-feed at Minneapolis Cologix.
Apparently the local utility requested that they move one side to
generator due to the weather and high-utilization, and the ATS failed.
But we're up ...

Being a Minnesota native, I can tell you that while it is indeed cold,

consistently the media overplays the severity of Midwest cold weather as
some kind of unique phenomenon. They amplify this by reporting the
wind-chill factor, which is the “what it feels like” equivalent in a
cold and windy environment. But equipment feels nothing, so windchill is
irrelevant.
For example, Minneapolis is -20F, but the news media instead reports
“-60F wind chill”, which, while dramatic, is not meaningful for most
purposes. I grew up in Minnesota with -30F and lower quite common, and
we walked to school in those temperatures. You just have to dress well.
Minneapolis is paved with tunnels and heated skyways to eliminate most
outdoor walking downtown.
As far as networks go, none of the ISPs I know of do anything different
than anywhere else in the country. Everyone has backup power. It’s
already common practice everywhere to exploit cooler winter ambient
temperatures to reduce HVAC requirements, so that’s not new either. But
it gets as hot in the Midwest in our summer as it is in SA for you now,
so everyone must still build out HVAC capacity to cover the hottest days.

For anyone running IP networks in the Midwest, are you having to do
anything special to keep your networks up?
For the data centres, is this cold front a chance to reduce air
conditioning costs, or is it actually straining the infrastructure?
I'm curious, from a +27-degree C summer's day here in Johannesburg.
