CoreSite's LA1 is its tenancy inside One Wilshire at 624 South Grand Avenue - the 30-story, roughly 664,000 sq ft tower that has been the West Coast's primary carrier hotel since its fourth-floor meet-me room was built out in 1992. CoreSite occupies 171,000-plus square feet of that building, about a quarter of its rentable area, and operates the meet-me room; the tower itself has been owned by GI Partners since 2013. The address carries 339 networks and five exchanges, among them Any2West, BBIX US-West, MegaIX Los Angeles and NYIIX Los Angeles, alongside trans-Pacific subsea cable landings. In August 2025 CoreSite finished replacing the building's legacy single-corded generator plant with an N+1 configuration, adding belly tanks for full-load runtime. High-count dark fiber ties LA1 to LA2 and LA3.
