? Why Johor is attracting data‑center development
• Proximity to Singapore’s submarine‑cable hub, offering low‑latency connectivity for global clients.
• Abundant land, water, and power supply (often coal‑based, but renewable in YTL’s case).
• Streamlined regulatory environment and government support, especially under Johor–Singapore Special Economic Zone goals.
• Massive investments from hyperscalers including Microsoft, Oracle, ByteDance, and others intensify demand for third‑party infrastructure in Johor         .
