Nothing against the NE but power rates in Atlanta are $0.045/kwh. Probably a third of what they are in the NE. May not sound like a lot but operating at high power loads for 24 x 365 adds up fast.
Most hosting operators have an IT background so I'm guessing that you have badnwidth, liscensing fees, etc.
On the reale state & business side:
Preventative Maintenance Contracts for HVAC, UPS, Generator, Fire Protection, Engineering support (on occassiion), General Maintenance & Repairs, Battery Replacement (every 5 years), annual fire alarm system certification for the city, circuit add/moves/changes, fuel for generator, security, legal and accounting fees, marketing (commissions, referral fees, discounts, etc.), general liability insurance, contents insurance, perhaps professional liability insurancs(???), cleaning, trash, POTS(voice) lines, fixtures furniture and equipment (Copier, Fax, Desks, Refrigerator, Coffee Pot etc.), retirement plan' Many of thes aren't very large but $1K here and there add up fast.
Don't forget to allocate time (another cost) for the management of all of these vendors and problem resolution.
Depending on your leas, lease Pass throughs such as CAM, Taxes, & Insurance
