This happens to be why my quarter rack space has only 2 1U computers in it. It was supposed to be a quarter rack (10U), but I was told I had only 7U of space. Okay, not a problem, I can put in 7 1U systems, 14 if I purchase the half sized systems. Then I was told I have only 2A, oh, and here's a switch that'll turn it off if you go over. Which means my quarter rack has two 1U servers in it.

Worse, even the full rack is allowed only 15A before you have to buy a secondary power conduit to the rack at this particular colo.

I suspect it's more a way for the facility to make money than it is to reduce energy usage. When I visited the facility last to move boxes, 4 racks were being emptied and a good 60% of them were completely empty anyway, so the facility may not be long in this economy.
 

I'm on my seventh different (Ameritrade-only) email address with Ameritrade. Rather than doing nothing, however, I both forwarded the spams I received to my Ameritrade-only email account to Ameritrade's contact-us-with-security-issues email address, and filed a report/complaint with the SEC.

After the first complaint of Ameritrade's privacy breach to the SEC, Ameritrade starting responding with more than just the boiler-plate "It's not our problem, it's yours" responses. I received feedback from the SEC and someone at Ameritrade with more than just a "customer service rep" title.

A little satisfaction. Not a lot.

Unfortunately, I still receive the spam. The address change to spam delay has increased to about 4 months, up from about 2 months a year ago.
