Equinix's large Sydney datacentre experienced an outage today flowing from a TransGrid electricity equipment fault in the Hunter Valley.
An equipment fault at TransGrid's Bayswater Substation in the Hunter Valley at 10:50am this morning knocked out power to the Equinix facility in Mascot, as well as electricity in several cities and states, according to state-owned energy wholesaler TransGrid.
Equinix spokespeople have been unable to respond to ZDNet.com.au's questions. Large datacentre providers usually have back-up generators available to cope with such power outages.
For example, rival datacentre operator Global Switch confirmed it was also affected by the outage; however, its backup generators kicked in and spared any disruption to customers, a spokesperson for the company told ZDNet.com.au.
"A joint effort from staff in NSW transmission and distribution organisations ensured that power supplies were progressively restored within an hour of the incident occurring," TransGrid's general manager of Network Performance and Operations, Lionel Smyth said in a statement this afternoon.
