Colocation in Los Angeles: One Wilshire, the submarkets, and an on-ramp gap worth knowing

One Wilshire, and why it dominates the market#

624 South Grand Avenue — One Wilshire — is the centre of the Los Angeles interconnection market and one of the most significant network buildings in the world. CoreSite's LA1 occupies it, at 171,000-plus square feet, with more than 300 on-net networks. By its operator's account the building carries roughly a third of all trans-Pacific internet traffic.

The practical consequence is that Los Angeles is a market where the building often matters more than the operator. If your requirement involves trans-Pacific routing, content distribution, media and entertainment delivery, gaming, or peering breadth on the West Coast, One Wilshire's ecosystem is not substitutable by a cheaper building with good carrier access — the value is the accumulated fibre convergence, and it took decades to accumulate.

CoreSite's three downtown buildings are dark-fibre tethered to one another, which means LA1, LA2 and LA3 function as one campus commercially while remaining three buildings for routing and resilience purposes. That is a genuinely useful property: it lets a buyer take cheaper space in one building while retaining access to the ecosystem of another.

The operator landscape#

Verified against operator-published material as of 26 August 2026. Los Angeles is a genuinely multi-submarket metro — downtown, the South Bay, and Orange County are separate markets with separate economics — so the city is named on every row.

Sites that look like supply and are not#

Four further Los Angeles-area Evocative site codes — LAX3, LAX13, LAX15 and LAX16 — are network-only points of presence. Evocative separates these from colocation on its own directory, and they should not be treated as capacity you can buy. Separately, phoenixNAP's Los Angeles location is a network node, not a colocation facility, though third-party directories count it as one.

This is the ordinary condition of the LA market rather than an unusual failure. Los Angeles has a very high ratio of network nodes to sellable colocation, precisely because One Wilshire and its neighbours attract network presence — so address-keyed listings inflate operator footprints here more than in most metros.

Where our verified record runs out#

We would rather publish that paragraph than a table that looks complete and is not. A market guide's gaps are more useful to a buyer than its confident filler, because a gap tells you where to ask a question.

Network and cloud ecosystem#

For peering and carrier density, Los Angeles is a strong market and One Wilshire is the reason. CoreSite's Any2Exchange operates here as Any2West, spanning Los Angeles and Silicon Valley; the operator describes Any2 as the second-largest internet exchange in the United States and the largest on the West Coast, with more than 400 member networks — that is CoreSite's own claim, and the member counts it publishes are aggregate rather than per-building.

The cloud on-ramp finding#

What is confirmed in this metro: Oracle FastConnect at 50G is confirmed for Los Angeles at metro level through CoreSite. Beyond that, our corpus holds no facility-level cloud on-ramp confirmation for Los Angeles at all — which is a statement about how little is published at building granularity, not a claim that on-ramps are absent.

For the other operators here, cloud access is partner-mediated: Evocative reaches AWS, Azure and Google Cloud through an interconnection partner across most of its colocation metros, with Los Angeles not individually confirmed among them, and DataBank's Santa Ana facility likewise reaches the clouds through a partner rather than a direct cross-connect. Both are workable; both are a hop away from a same-building on-ramp.

The practical instruction for this metro is the same as everywhere but matters more here because the marketing is denser: ask whether the on-ramp for your specific cloud region is physically present in the building being quoted, or reached over a network. In Los Angeles you should expect the second answer more often than the first.

The submarkets are further apart than they look#

Los Angeles rewards being specific about geography in a way that Dallas or Phoenix do not, because the metro is enormous and its traffic is famously punishing. Three practical submarkets appear in the verified set.

• Downtown — One Wilshire and the CoreSite campus at Grand, Alameda and Bauchet. The interconnection core, the highest cost, and the right answer when network value is the requirement.
• The South Bay — Redondo Beach and El Segundo. Historically strong for media and aerospace-adjacent customers, and roughly fifteen to twenty miles from downtown, which is a meaningful drive rather than a short one.
• Orange County — Santa Ana and Irvine, roughly forty miles from downtown. A genuinely separate market with its own customer base, frequently filed under "Los Angeles" by operators and rarely interchangeable with it in practice.

If you have staff who will physically visit the facility, the submarket is a real operational cost and should be part of the decision. If you never will, it is mostly a latency and cost question — and the submarkets differ on both.

When Los Angeles is the right metro — and when it is not#

It fits when#

• Trans-Pacific routing or Asia-Pacific reach is part of the requirement. This is the market's strongest and least substitutable argument, and it concentrates in one building.
• You are in content, media, entertainment, gaming or advertising technology. The ecosystem and the peering density here were built around exactly those workloads.
• You need West Coast presence with genuine carrier choice, as distinct from simply being on the West Coast.
• You need high-density or AI-ready space with liquid cooling in the metro — CoreSite's LA3 is specifically equipped for it, which is a narrower field than the market's general marketing suggests.

It does not fit when#

• Cost per kW is your primary criterion. California power and real estate make this an expensive market, and if you will not use the interconnection value you are paying for someone else's requirement. Phoenix and Las Vegas exist substantially because of this trade.
• Seismic exposure is a hard constraint in your risk model and you are not prepared to design around it.
• You need very large contiguous new capacity. This is a dense, mature, constrained urban market, not a greenfield campus market — Dallas and Phoenix are better questions for that.
• A private AWS connection in the building is non-negotiable and you have not confirmed it in writing for the specific facility. See the on-ramp finding above.

When the big brands are the right answer#

CoreSite is genuinely the right answer in Los Angeles more often than not, and this page would be dishonest if it pretended otherwise. One Wilshire is the market, the three-building dark-fibre campus is a real architectural advantage, and LA3's liquid cooling addresses a requirement most of the metro cannot. Equinix is the right answer when you need its global contract and its fabric across many metros and Los Angeles is one leg of that — with the on-ramp caveat above confirmed explicitly.

Where the mid-tier competes hardest here is on cost for deployments that do not need the downtown ecosystem — a South Bay or Orange County requirement, or a disaster-recovery leg. That is a real and frequently overlooked option, and it is the reason to name Evocative and DataBank on a page like this at all.

Pricing context for Los Angeles#

No operator in this market publishes a rate card — pricing is quote-only and sales-engineer-gated across the board, as it is throughout colocation. We publish no per-operator figures, for the reasons set out in how to run a colocation bid.

For orientation only: CBRE's H2 2025 North American report put retail colocation asking rates at roughly $196 per kW per month for 250–500 kW deployments against a record-low 1.6% North American vacancy rate. Los Angeles sits above that continental blend rather than at it — carrier-hotel space in a constrained coastal market is priced accordingly.

Two commercial observations specific to this metro. First, the premium is concentrated and it is separable: the downtown interconnection premium is real, and the dark-fibre tethering between CoreSite's buildings is precisely the mechanism for taking cheaper space while retaining ecosystem access — worth asking about explicitly rather than accepting the most expensive building by default. Second, cross-connect economics matter more here than in most markets, because deployments in a building with 300-plus on-net networks tend to run more connections. Model the connection count over the full term before comparing offers; in a dense One Wilshire deployment it can rival the space and power line.

What this page deliberately does not tell you#

Who has space. Every figure above describes a building, never what is unallocated. In a constrained coastal market with very little new construction, that gap is the entire question — and it is answerable only by asking each operator at the moment you need to know.

This page is also, as noted above, incomplete on Digital Realty and Csquare in this metro, and we would rather you knew that than assumed the table was the market. The sample reports show what a complete set of operator answers looks like once they come back.
