[AusNOG] OT: Brisbane Storm. Gentlemen, start your engines..

[Narelle]

I'd have kittens if you tried to do that in any of the DC facilities
I've designed. Fire risk, chemical hazards...

Then again, if you were prepared to pay extra, cover the liabilities
AND you were big enough and  with pockets deep enough, the commercial
folks might do a deal...

And I'd still think it silly.
