Quick answer: If you’re searching for “Cyxtera,” the company doesn’t exist under that name anymore. It went through Chapter 11 bankruptcy in 2023, was acquired by Brookfield in early 2024, rebranded as Centersquare that same year, and converted into a new legal entity called Csquare, Inc. in June 2026 — right before filing for a US IPO. If you have an old Cyxtera contract or SLA on file, it’s now with Csquare. It’s now a publicly traded company (NYSE: CSQR) as of July 2026
Cyxtera was, for years, one of the better-known names in enterprise colocation — the kind of vendor that showed up in network diagrams, vendor-risk spreadsheets, and procurement contracts across the industry. If you’re reading this because “Cyxtera” turned up in an old document and the company’s website doesn’t seem to exist anymore, you’re not imagining things. The name has changed twice since 2024, and here’s the full trail.
From a CenturyLink Spin-Off to a $2.8 Billion Data Center Company
Cyxtera was formed in May 2017 through a $2.8 billion transaction that pulled 57 data centers out of CenturyLink, combined with cybersecurity and analytics assets from Medina Capital. It grew into a global colocation and interconnection provider, went public via a SPAC merger in 2021 under the ticker CYXT, and for a while looked like a stable, established infrastructure vendor — similar in market position to how Vblock once held a foothold in converged infrastructure before fading out.
Here’s what the original Cyxtera brand looked like before any of these changes happened:

Bankruptcy and the Brookfield Acquisition
That stability didn’t last. Cyxtera filed for Chapter 11 bankruptcy in June 2023, and by November that year it had confirmed an agreement for Brookfield Infrastructure Partners to acquire substantially all of its assets for $775 million, through a court-supervised process.
The deal wasn’t a simple one-line sale. Brookfield also purchased the real estate underlying seven of Cyxtera’s US data centers from separate landlords, Cyxtera separately renegotiated its lease terms with Digital Realty to exit several sites in 2024, and it sold off its Montreal and Vancouver operations to Cologix entirely. The acquisition closed in January 2024.
📌 Bankruptcy Doesn’t Always Mean Shutdown: A vendor filing Chapter 11 doesn’t necessarily mean service stops — Cyxtera kept operating through the court-supervised sale, and customers were transitioned rather than cut off. The practical risk isn’t sudden downtime; it’s outdated vendor names sitting in contracts, compliance records, and architecture diagrams long after the company itself has changed hands.
Centersquare: The First Rebrand
In April 2024, Brookfield merged Cyxtera with its other data center holding, Evoque, under a new combined brand: Centersquare. At the time, the new company reported 400MW of capacity across 1.9 million square feet of space, with 200MW of potential expansion capacity, and Evoque’s CEO, Spencer Mullee, was appointed to lead the combined business.
Centersquare kept growing from there — by October 2025 it had acquired 10 more data centers across the US and Canada, bringing its total footprint to 80 facilities.

Csquare: The Second Name Change, and Its July 2026 IPO
The most recent change happened quietly. According to its SEC S-1 filing, the entity previously operating as “BIF III US Aggregator (Delaware) LLC” converted into a Delaware corporation on June 15, 2026, under a new name: Csquare, Inc. The company is Dallas-based, majority-owned by Brookfield Corporation through Dawn Topco L.P., and now operates 64 data center sites across the US, Canada, and the UK.
This conversion set up a public listing. Csquare confidentially filed for a US IPO on April 24, 2026, then filed publicly in June 2026. Its filing disclosed Q1 2026 revenue of $270.5 million against a net loss of $66 million — up from $232.8 million in revenue and a $34.9 million net loss in the same quarter a year earlier, roughly 16% year-over-year growth.
The IPO itself followed quickly. Csquare priced its shares at $21 on July 15, 2026 — $2 below its marketed range of $23 to $27 — selling 50 million shares to raise $1.05 billion. Trading began the next day on the New York Stock Exchange under the ticker CSQR, and the stock slipped roughly 2.6% on its debut, closing below the IPO price. Brookfield retained about 67% of the company’s voting power after the offering, and most of the proceeds are earmarked to pay down a portion of Csquare’s roughly $5 billion in outstanding debt — a detail analysts flagged as a concern going into the listing.

What This Means If You Have (or Had) a Cyxtera Contract
For IT and procurement teams, this is less a cybersecurity story and more a vendor-lifecycle one — the same category of problem covered in our look at whether aging hardware like the Cisco ISR 4451-X is still supportable after end-of-life.
✅ Update the Paper Trail, Not Just the Contract: If “Cyxtera” still appears in a vendor-risk register, a DR/BCP plan, or an architecture diagram, that’s worth correcting regardless of whether the underlying service changed. A structured record of who owns the update and when it was last checked is a lot more useful six months from now than a one-time fix nobody logged.
An upcoming IPO also means more public disclosure than a privately-held infrastructure vendor normally provides — financials, customer concentration, litigation risk, all become part of the public record. If your organization depends on Csquare for colocation or interconnection, that filing is worth a read before renewal time.
Frequently Asked Questions
What happened to Cyxtera?
Cyxtera filed for Chapter 11 bankruptcy in June 2023. Brookfield Infrastructure Partners acquired substantially all of its assets for $775 million in a deal that closed in January 2024. The company then merged with Brookfield’s other data center holding, Evoque, and rebranded as Centersquare in April 2024.
Is Centersquare the same company as Cyxtera?
Functionally, yes — Centersquare is the successor brand that Cyxtera’s assets and operations became after the Brookfield acquisition and Evoque merger. It’s not a new, unrelated company; it’s Cyxtera’s infrastructure and customer base operating under a new name and ownership.
What is Csquare, and how is it different from Centersquare?
Csquare, Inc. is the legal entity Centersquare converted into on June 15, 2026, ahead of filing for a US IPO. It’s the same underlying business — Brookfield-owned, Dallas-based, operating data centers across the US, Canada, and the UK — just under a new corporate name and structure suited to going public.
Is Csquare going public?
Yes. Csquare confidentially filed a draft S-1 with the SEC in April 2026, then filed publicly in June 2026. As of that filing, it reported Q1 2026 revenue of $270.5 million against a $66 million net loss, and operates 64 data center sites.
If I have an old contract with Cyxtera, who do I contact now?
Your service relationship would now run through Csquare (formerly Centersquare, formerly Cyxtera) — the underlying facilities and customer agreements transitioned through each ownership change rather than being terminated. It’s worth confirming directly with your account team, since contract terms or points of contact may have changed across the transitions.
