Item 1. Security and Issuer
This Amendment No. 17 to Schedule 13D on the Common Stock of Internap Network Services Corporation  (the “Issuer”) is being filed on behalf of the undersigned to amend the Schedule 13D, as amended  ( the “Schedule 13D” ), which was originally filed on May 23, 2011.  Unless otherwise indicated, all capitalized terms used herein but not defined herein shall have the same meanings as set forth in the Schedule 13D.
Item 2. Identity and Background
Item 2 to Schedule 13D is amended, in pertinent part, as follows:
