A total of 11,698 listings from 3,249 operators, based on the geographic filtering below:

One physical location can have multiple listings, for example if it is a campus or multi-tenant building with multiple data centers.
For such a location the campus or multi-tenant building will count as one listing, and each data center on site for another listing.
Data centers will refer to campus/building listings as parent listings, via a reference to their unique ID.

How is your data sourced?

Our data originates from multiple sources, primarily:
  • Operators: Data center operators and service providers use Data Center Map as a marketing tool, to promote their data centers, networks and services to potential clients. They have direct access to add and update listings.
  • External sources: We monitor multiple external databases, to identify missing or changed listings. They are automatically queued for manual review.
  • Manual sourcing: We manually identify operators that we are missing and manually add them to our database.
  • End-users: End-users send us tips and requests, about missing or outdated listings, that we manually handle.

How complete is your data?

As there are no regulatory requirements to register data centers in a central database, there are no complete resources available. All databases are based on voluntary data submissions and/or collecting data from providers or other sources.

With our database dating back to 2007, we have one of the oldest and most comprehensive databases in the industry. Covering thousands of records on a global basis in this constantly changing industry, it is of course by no means 100% complete.

The database will always have missing listings as well as incorrect, incomplete or outdated listings. Most frequent reason for outdated listings is M&A.

How often is your data updated?

Our data is updated on a daily basis, by providers updating their listings, us updating listings as well as our systems automatically collecting data from external databases and systems. There will always be outdated or incorrect records in the dataset, despite our best efforts to keep the data up to date.

What kind of data centers do you cover?

We primarily track data centers from operators offering colocation or cloud services, but also select crypto miners and hyperscale operators (incl. Amazon, Microsoft, Google, Meta and Apple).

We currently do not cover enterprise data centers or government data centers.

How is your data structured?

Data center operators describe and market their assets in different ways. For example, one operator may market a campus with four buildings as a single data center, while another may market each building as a separate data center. To make comparisons possible across these different approaches, we normalize all data using a consistent and flexible structure.

Listing Types
Our database is organized into the following listing types, with some of them having the ability to have other listings as parent or child listings. Such relationships are easily identifiable through the parent_id in our exports:
  • Land:
    Land-banked locations where no concrete data center construction plans are yet known.
    Land listings can not have parent or child listings.
  • Campus:
    A parent listing representing a group of data center buildings clustered on the same site.
    Campus listings can not have parent listings, but may have one or more Facility listings as children.
  • Multi-Tenant Building:
    A parent listing representing a single building that hosts multiple, independently operated data centers.
    Multi-Tenant Building listings can not have parent listings, but may have one or more Facility listings as children.
  • Facility:
    An individual physical data center that meets our listing requirements. A facility may occupy an entire building or one or more rooms within a building.
    Facility listings can have a Campus or Multi-Tenant Building listings as parents.
    In some edge cases a Facility may be parent/child of a Facility, for example where a wholesale data center operator is leasing out part of their facility to a colocation provider.
This structure allows us to model relationships properly between assets and do consistent comparisons accross operators.

Counting Methodology
To ensure transparency and consistency, we adopted the following counting methodology by end of year 2025:
  • Unique Locations: This metric represents the number of distinct physical sites, counting all listing types without a parent listing.
  • Unique Facilities: This metric represents the number of individual data center facilities. We count all Facility listings that have no parent or have a Campus or Multi-Tenant Building as parent. In cases where a Campus is known but the exact number of buildings is unclear, we count the Campus as one Facility.
For data center counts on our website, the unique facilities count will be used.

Does your database include data centers under development?

Yes, we track data centers in the following stages of their lifecycle:
  • Land Banked
  • Planned
  • Under Construction
  • Operational
Lifecycle stages should only be considered indicative, as it is very hard to track when stages change.

Can we get a copy/export of your data?

We offer exports of our data in many different formats, please review our Data Explorer for further details, or reach out to us to let us know more about your needs.

My company or some of our data is missing, how can we fix this?

Please sign up for a free account. Once you are signed up and logged in, you will be able to add and update listings. If your company already has an account, you will be presented with the option to be assigned to this account (pending our approval).

How does blue and green markers on the map differ?

Green markers represent premium members (paid listings), while blue markers represent free listings.
