Market snapshot

Ashburn at a glance

Derived from the facility records we hold, not from vendor claims. Where a figure is missing from the record it is left out rather than estimated.

Operator concentration

48% of facilities

Digital Realty, Centersquare and Equinix account for 29 of 60 recorded sites, the rest spread across 19 operators.

Carrier neutrality

57% confirmed neutral

Neutral 34Single‑carrier 26Unverified 0

0 sites carry no neutrality statement we could verify. They are shown as unverified, never as neutral.

Recorded floor space

4.41M sq ft

Across 36 of 60 sites. The other 24 publish no floor area, so the real total is higher — we do not model the gap.

How this page is built

Facility records come from operator disclosures and public industry sources, normalised into a single schema and reviewed by hand. Events and roles are matched to this market through the same city list, so a market cannot appear twice under two spellings.

An operator who wants an entry corrected or expanded can claim it below. Corrections are free and always will be.
