I know this is kind of a commercial post, but bear with me. I have not been paid for this post but seeing that some companies might have an interest in colocation or access to the Auckland’s Sky Tower facilities I accepted the content to post in this thread. Basically the Sky Tower is not only a premium telecommunications and broadcast tower but also accommodates many Internet Service Providers on two glass clad floors 200 metres above sea level. 

It features: 

• Two fully redundant 3 phase mains supplies with separate 11 KV feeds, both backed up by generators
• Robust, monitored air conditioning
• Full interconnectivity to other Tower users’ equipment
• Unprecedented wireless coverage over Auckland
• 24/7 access for nominated staff and contractors
• 24/7 on site security
• Central location
• Free underground parking while on site
• No interconnection fees

 Anyone interested in exploring the opportunities offered at Sky Tower for their business should contact Warren at jda.co.nz (and that's his email too).
