I still maintain that the article is inaccurate.
1. How does the Uptime Institute define "supplier", I can't find anything on their website, and I still assume this to mean the immediate supplier to the data centre, not the producer. The article uses the vague term "power provider". Does it mean producer, distributor or reseller?
2. We have multiple power producers in South Africa, we have multiple power distributors in South Africa, and we have multiple power resellers in South Africa. What exactly is stopping Vodacom from obtaining a second, independent supply?
3. If Vodacom can obtain a second supply, why does the article say that they CAN'T achieve tier 4 status. If they say that they haven't, then they haven't, but this doesn't mean they can't.
I might not be fully familiar with data center rating, but I am fully familiar with the interpretation of standards, and the design and supply of power systems. What exactly do you find inaccurate in my comments.
