Good old 'cloud'.
Thing is that it wouldn't be so kack if these co-called service providers weren't so cheap when building out their infrastructures.
Its not only a matter of UPS's but also generators. There should not be any excuse for a DC to be down because a sub station has been hit and is out for several days. Especially if its meant to be a high availability DC.
Of course if the company is willing to take the hit fair enough. I hope in that case they are not selling five nines availability to their customers.
