Yes—Zayo acquired Corelink Data Centers, LLC. The transaction was an asset purchase agreement signed and completed on August 1, 2013. Zayo reported that it acquired substantially all of Corelink’s net assets for approximately $1.9 million.
That amount consisted of approximately $1.6 million in 301,949 preferred units of CII and approximately $0.3 million in cash, net of cash acquired. The deal was not a recent 2026 acquisition, and the filings do not describe it as a simple purchase of every corporate interest, contract, liability, employee, or facility associated with Corelink.
The exact CoreLink-Zayo transaction
The acquired legal entity was Corelink Data Centers, LLC. Zayo’s later filings describe the transaction as an acquisition of substantially all of Corelink’s net assets under an asset purchase agreement. Both the agreement date and closing date were August 1, 2013.
The primary evidence is Zayo’s SEC reporting, including its 2015 Form 10-K. Later filings continued to list Corelink as one of Zayo’s historical acquisitions.

How much did Zayo pay?
| Component | Reported amount |
|---|---|
| Total consideration | Approximately $1.9 million |
| CII preferred units | 301,949 units valued at approximately $1.6 million |
| Cash | Approximately $0.3 million, net of cash acquired |
| Cash-flow statement amount | Approximately $0.251 million, net of cash acquired |
The approximately $0.251 million figure should not be treated as the total purchase price. It represents the net cash-flow amount shown for the acquisition. The broader approximately $1.9 million consideration included the noncash preferred-unit component.
Similarly, the $1.6 million assigned to the preferred units was an estimated fair value reported for accounting purposes. It was not cash paid directly to the seller.
Asset purchase versus stock purchase
Zayo described the deal as an asset purchase for financial-reporting purposes. In plain English, that means the transaction was structured around acquiring the business’s assets and related net assets rather than being presented simply as the purchase of all outstanding equity in Corelink.
The same filing says the transaction was considered a stock purchase for tax purposes. Those descriptions are not contradictory: accounting and tax rules can characterize the same transaction differently. The clearest general description is that Zayo acquired substantially all of Corelink’s net assets through an asset purchase.

What assets did Corelink bring to Zayo?
Zayo’s acquisition schedules identified several Corelink asset categories. The 2014 Form 10-K reported approximately:
- $93,000 in cash;
- $521,000 in other current assets; and
- $15.856 million in property and equipment.
These figures should not be confused with the purchase consideration. The approximately $1.9 million describes what Zayo reported giving in exchange for the transaction. The property-and-equipment figure is an acquisition-accounting value assigned to acquired assets. Accounting schedules can also include liabilities, purchase-accounting adjustments, and other items, so the categories do not function as a second purchase-price calculation.
What kind of business was Corelink?
Zayo grouped Corelink with several smaller fiscal-2014 acquisitions involving dark fiber and colocation-oriented businesses. That supports describing Corelink Data Centers as a data-center and colocation-related business with connectivity relevance.

However, the filings reviewed do not provide a complete standalone profile of Corelink’s facilities, network mileage, customers, employees, or product catalog. Claims about a precise number of locations or the automatic transfer of every contract and employee would go beyond the public evidence.

Why did Zayo make the acquisition?
Zayo stated that acquisitions generally helped the company:
- increase operating scale;
- improve operating leverage;
- extend network reach; and
- broaden its customer base.
Corelink reasonably fits within that broader expansion strategy, particularly in colocation and connectivity infrastructure. But the available filings do not quote a separate, Corelink-specific rationale from Zayo management. It is more accurate to present the strategic connection as an informed interpretation of Zayo’s stated acquisition program, not as a uniquely documented reason for this transaction.
When did Corelink affect Zayo’s financial results?
Zayo reported that revenue and operating expenses increased beginning August 1, 2013, the closing date of the Corelink transaction. That indicates the acquired business was included in Zayo’s operating results from the acquisition date rather than from a later integration milestone.
How Corelink compared with other Zayo acquisitions
Corelink was one of several acquisitions associated with Zayo’s fiscal 2014 expansion. Zayo also listed:

| Acquisition | Date |
|---|---|
| Access Communications | October 1, 2013 |
| FiberLink | October 2, 2013 |
| CoreXchange | March 4, 2014 |
| Geo Networks | May 16, 2014 |
Zayo characterized the first group as smaller dark-fiber or colocation-oriented transactions. Geo Networks was different: Zayo described it as a substantially larger European dark-fiber and wavelength-services acquisition. Corelink was therefore part of a broader infrastructure buildout, but the available evidence does not support calling it a transformational takeover.
The relevant historical disclosures appear in Zayo’s 2014 Form 10-K and September 30, 2014 Form 10-Q.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What happened to the Corelink name?
The public filings confirm the acquisition and later identify Corelink as part of Zayo’s acquisition history. They do not establish a definitive date when the Corelink brand was retired, whether every legacy service was migrated, or what happened to each facility, customer contract, employee, or vendor relationship.
Recommended Free Tools
Accordingly, it would be unsafe to say that Corelink immediately disappeared or that all Corelink operations automatically transferred to Zayo. Anyone researching a legacy account or service should use current Zayo or successor support channels rather than assume that a historical Corelink name remains a current product label.

Zayo’s 2016 Form 10-K continued to identify Corelink as a historical acquisition, but that does not by itself resolve the current status of the brand or individual services.
Common points of confusion
- Corelink Data Centers versus CoreXchange: These were separate acquisitions listed by Zayo at different dates.
- Corelink versus Core NAP: Similar names do not establish that the entities were the same business.
- $251,000 versus $1.9 million: The former is the reported net cash-flow amount; the latter includes noncash preferred-unit consideration.
- “Bought the company” versus “acquired the net assets”: The shorter phrase is acceptable shorthand only when the asset-purchase structure is explained.
- Historical acquisition versus current service: A 2013 acquisition does not prove that a Corelink-branded product, facility, or contract remains available in 2026.
Bottom line
“CoreLink acquired by Zayo” is accurate shorthand, provided it is qualified. The technically precise description is that Zayo entered into and completed an asset purchase for substantially all of the net assets of Corelink Data Centers, LLC on August 1, 2013. Zayo reported approximately $1.9 million in consideration, made up of preferred units and cash.
The transaction helped fit Corelink into Zayo’s broader dark-fiber, colocation, and connectivity expansion, but the available filings do not establish a complete post-acquisition history for the Corelink brand, personnel, customers, or facilities.
