I dont' think "giga"switches need any help from the ambient temperature to
lose packets.  8-)

I recall seeing a study a few years back that showed direct correlation
between packet loss and temperature on DEC Gigaswitches; does anyone else
remember this?

Temperature readings:
        chassis inlet    measured at 26C/78F

78F in my cabinet in the inlet seems reasonable to me.

Well seeing as we're playing this game:

Brrrr...

PAIX is the only place I worry about my equipment getting too cold,
condensation and such.  Anyone know what the dewpoint at PAIX is?
Any other entrants in the cold co-locate arena?

Of course, WCOM wins for having the hottest POPs.
