Here are the top colocation facilities and operators in the Amsterdam market (why they’re notable and what they’re best for). I’ve focused on network-dense, carrier‑neutral sites and large campus operators that customers commonly pick for low latency to Europe, scale, compliance and interconnection.

1. Equinix (AM1 / AM2 / AM3 / AM4 / AM5 / AM6 / AM7 / AM8 / AM11)

• Why: Industry-leading interconnection ecosystem, many metro sites at Science Park and Westpoort, direct access to AMS‑IX and many cloud providers, extensive carrier community and strong sustainability/certifications. Good for enterprises and multi‑cloud/low‑latency use cases. (Equinix.com)

2. Digital Realty / Interxion (Amsterdam Data Tower and Science Park sites)

• Why: Large carrier‑neutral footprint in Science Park (Digital Realty’s PlatformDIGITAL/Interxion assets), strong connectivity to AMS‑IX, good for enterprises and hyperscalers needing dense peering and multi‑floor deployments. (prnewswire.com)

3. Iron Mountain (Amsterdam campus, AMS‑1)

• Why: Very large campus near Haarlem/Schiphol with hyperscale capacity, strong compliance posture (ISO, SOC, PCI etc.), 100% matched renewable power options and a big carrier ecosystem — good for regulated industries and large-scale builds. (ironmountain.com)

4. Global Switch (Amsterdam Data Centre Campus)

• Why: Large scalable campus in Slotervaart/Overtoomseveld, high carrier density and direct access to AMS‑IX/NL‑IX; suitable for bespoke multi‑MW requirements and customers wanting campus-level scale. (globalswitch.com)

5. NTT / e‑shelter (AMS1 campus)

• Why: Major European operator (e‑shelter / NTT) with a Schiphol‑Rijk campus offering wholesale + retail colo, large power capacity and carrier options — good if you want a single operator with global reach and hybrid cloud options. (services.global.ntt)

6. EvoSwitch (AMS‑01 / Haarlem)

• Why: Energy‑efficient, green‑focused operator with a large modular facility near Schiphol (carrier options and adiabatic cooling). Often chosen for green credentials and flexibility. (evoswitch.com)

7. EdgeConneX, Keppel/CloudHQ and other campus players

• Why: Several other operators (EdgeConneX, CloudHQ/Keppel and smaller regional colo providers) have developed AMS campuses near Schiphol and Science Park recently; choose these for specific wholesale or edge requirements or when you need space/power that larger retail sites may not have. (examples and footprints vary by campus). (baxtel.com)

How to choose between them (quick checklist)

• Connectivity & peering: check presence of AMS‑IX, NL‑IX and the carrier list at the specific site.
• Latency/Location: Science Park is the typical low‑latency hub for EU traffic; Schiphol area has many hyperscale campuses.
• Power & density: verify per‑rack kW and campus expansion plans if you expect growth.
• Compliance & certifications: ISO 27001, SOC, PCI, and local/regulatory requirements matter for finance/health customers.
• Sustainability: if renewable energy or low PUE matters, confirm the operator’s energy mix and PUE claims.
• Commercial model: retail vs wholesale, contract length, cross‑connect fees, and Smart‑Hands rates.
• Physical access & remote services: 24/7 access policy, courier access, and on‑site engineering support.

If you’d like, I can:

• Compare 2–3 specific facilities side‑by‑side (power per rack, pricing indicators, carrier list, certifications) — I’ll look up current availability and recent pricing/quotes. (Note: for current availability or exact pricing I’ll fetch live info.)
• Or search specifically for carrier lists or certifications for any one of the facilities above.

Which comparison would you like me to run next?
