南非將數據中心列為「關鍵」地位

🔑 增強重點摘要

• •South Africa's data center market is projected to grow from USD 0.67 billion in 2026 to USD 1.44 billion by 2031 at a CAGR of 16.35%, driven by Tier 3 facilities dominating 89% of revenue for reliability amid grid instability[1].
• •Teraco expanded its Johannesburg campus with JB7 in November 2024, adding 30 MW capacity via a ZAR 8 billion loan, while hyperscalers like Microsoft (2019) and others have invested in local infrastructure[1][2].
• •South Africa hosts 61 data centers, the most in Africa, supporting data sovereignty but facing challenges like chronic load shedding and high water/electricity demands for cooling[5].
• •May 2024 National Data and Cloud Policy mandates domestic storage for security data and 99.995% uptime for public workloads, alongside investments over USD 1.2 billion from AWS, Microsoft, Teraco, and Equinix[1][4].
