Frequently Asked Questions

Why is colocation data centre London Europe's largest market?
London hosts LINX (one of the world's largest internet exchanges), is Europe's financial capital, and lands transatlantic submarine cables. 274 facilities operated by 110 providers across the metro. Equinix, Digital Realty and NTT alone exceed 45% of installed MW.
Slough or Docklands — which?
Slough wins for financial trading (Equinix LD4-LD9, sub-59ms to NYC, larger floor plates, cheaper power than central). Docklands wins for interconnection density (LINX peering, Telehouse, highest UK carrier diversity). Royal Docks emerging for AI.
What about regulatory considerations?
FCA (Financial Conduct Authority) requirements drive financial services colocation strategy. UK GDPR and ICO rules apply. Brexit didn't materially change colocation strategy — UK remains a top European data centre destination with continuing EU connectivity.
Is London expensive?
Yes — among Europe's most expensive markets. Slough/Docklands financial corridors command premium rates. Royal Docks and outer London builds offer 30-40% lower per-kW pricing for AI/enterprise workloads where premium interconnection isn't critical.
