Here’s a concise overview of the main colocation data‑center options in the Amsterdam market (major campuses, who operates them, and a short note on what they’re known for).

Major providers / campuses (examples and notes)

• Equinix — multiple IBX sites across Amsterdam (AM1, AM2, AM3, AM4, AM5, AM6, AM7, AM8 / Science Park and Zuidoost campuses). Very strong interconnection ecosystem, direct cloud on‑ramps (AWS Direct Connect, etc.) and proximity to AMS‑IX / NL‑IX. (AMS-IX.net)
• Digital Realty (including former Interxion footprint) — large Amsterdam buildings/campuses (listed on AMS‑IX as Digital Realty / AMS17 and others). Strong wholesale and carrier‑neutral multi‑tenant options. (AMS-IX.net)
• Iron Mountain (including the former EvoSwitch campus) — large, connectivity‑rich campus near Haarlem/Amsterdam (J.W. Lucasweg), hyperscale‑ready capacity and sustainability focus; EvoSwitch Amsterdam facilities were acquired by Iron Mountain. (ironmountain.com)
• Global Switch — large multi‑tenant data center(s) in Amsterdam with significant carrier presence. (Listed on AMS‑IX colocations.) (AMS-IX.net)
• NorthC / Colt locations (recent market activity) — Colt Technology Services sites in Amsterdam were part of a sale to NorthC / funds managed by DWS (affects ownership/management of some colo facilities). Good to check current operator for specific sites. (cincodias.elpais.com)
• Other regional / specialist colos — many Dutch and international operators (NTT, euNetworks, smaller local colo providers and neutral carrier hotels) operate AMS presence and are listed as AMS‑IX colocation partners. Choose based on connectivity needs. (AMS-IX.net)

Why Amsterdam matters (short)

• Amsterdam is one of Europe’s largest network hubs (AMS‑IX / NL‑IX present), so you get very dense connectivity, low latency to European networks, and many cloud on‑ramps. Many global and regional colo players have multiple sites here. (AMS-IX.net)

Quick advice for choosing

• If you need maximum interconnection and cloud on‑ramps: look at Equinix (Science Park / AM campuses) or Digital Realty sites. (newsroom.Equinix.com)
• If you need large campus / hyperscale capacity and sustainability commitments: consider Iron Mountain (EvoSwitch campus) or Digital Realty. (ironmountain.com)
• If cost or smaller deployments matter: evaluate local/regional colocation providers and carrier hotels (they often have lower entry costs). Check carrier lists and AMS‑IX presence for the sites you shortlist. (AMS-IX.net)

If you want, I can:

• produce a short checklist/RFP template for requesting quotes (power density, SLA, interconnect options, certifications, pricing model), or
• compare 3 specific Amsterdam sites/providers on capacity, connectivity, certifications and estimated pricing (if you give the three names).
