The record, newest first

  1. Digital Realty lists EWR20 at 183,000 square feet in seven stories and EWR21 at 215,000 square feet in three stories. (Digital Realty, Nov. 2026; Digital Realty, Nov. 2026; Digital Realty, Nov. 2026)

  2. GI Partners was reported to have bought 2 Peekay Drive, with Telx staying on as its long-term exclusive tenant and operator; the article describes a two-building campus with 100 Delawanna. (Data Center Knowledge, Nov. 5, 2013; NJ Tech Weekly, Jan. 30, 2013)

  3. Ground was broken on a three-story, 215,000-square-foot Telx building at 2 Peekay Drive, with a stated $200 million investment. (Mountain Development Corp., June 11, 2012)

  4. Mountain Development was reported planning a data center of about 212,000 square feet at 2 Peekay Drive, a site that had housed a chemicals business, next to the Mountain Tech Center, where Telx was the anchor tenant. (Data Center Knowledge, May 12, 2011)

Conflicts and open questions

  • Square footage adds the two buildings as Digital Realty lists them. Digital Realty does not call them a campus on these pages; they are grouped because the addresses adjoin (about 400 meters apart by Census geocoder), and 2013 reporting described them as one campus.
  • Digital Realty's EWR21 page mentions a 730,000-square-foot Piscataway campus; that figure belongs to its Piscataway site, not Clifton, and is not used here.
  • Who owns 2 Peekay Drive today was not checked; the GI Partners purchase is from 2013.
