Item 1.01. Entry into a Material Definitive Agreement.

On February 4, 2011, DuPont Fabros Technology, L.P., a Maryland limited partnership (the “Borrower”), the operating partnership of DuPont Fabros Technology, Inc., a Maryland corporation (the “Company”), the Company and all of the Borrower’s subsidiaries that currently guaranty the obligations under the Company’s Indenture governing the terms of its 8 1/2% senior notes due 2017 entered into a First Amendment to Credit Agreement (the “First Amendment”), dated May 6, 2010 (the “Credit Agreement”), with KeyBank National Association (“KeyBank”), as administrative agent and a lender, and the other lending institutions that are parties thereto.

The First Amendment reduces the rate at which borrowings under the Credit Agreement will bear interest. Specifically, the First Amendment (i) removes the 1% floor that the Credit Agreement previously established for LIBOR, and (ii) provides that borrowings under the Credit Agreement will bear interest, at the Borrower’s election, at (x) LIBOR plus a margin ranging from 325 basis points to 425 basis points (in lieu of a fixed margin of 450 basis points) or (y) a base rate plus a margin ranging from 125 basis points to 225 basis points (in lieu of a fixed margin of 300 basis points), in each case, with the actual margin determined according to the ratio of the Borrower’s total indebtedness to gross asset value in effect from time to time.

Except as amended by the First Amendment, the remaining terms of the Credit Agreement remain in full force and effect.

The foregoing does not purport to be a complete description of the terms of the First Amendment, and such description is qualified in its entirety by reference to the First Amendment, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and are incorporated herein by reference.

From time to time, the Company has had customary commercial and/or investment banking relationships with KeyBank, Macquarie Capital (USA) Inc., Royal Bank of Canada, Bank of America, N.A., Raymond James Bank, FSB, and Jefferies Group Inc., and/or certain of their affiliates, all of which are also lenders under the Credit Agreement.
