Data centre operator Polaris has blamed an unnamed equipment vendor for what it says was a 24-minute power outage to a quarter of its data floor on Friday.
ZDNet Australia reported the outage affected banks, government departments and transit providers in Queensland.
Facility manager Dalkia said in a statement today that a representative from a vendor partner "was on-site performing scheduled maintenance and testing activities... when a partial power interruption occurred.
"This caused 25 percent of the facility to be without power for a period of less than 24 minutes, unfortunately impacting the ICT systems of some customers," a Dalkia spokesman said.
Dalkia is now reviewing the manual processes available to vendor representatives when entering the facility to perform maintenance.
"Dalkia has been working with the equipment vendor in question to review the situation and implement the necessary resolution to ensure that a repeat of this regrettable interruption cannot occur in the future," the company said in a statement.
Polaris customers have otherwise enjoyed 99.998 percent uptime at the facility, the facility manager stated.
Polaris was recently chosen as NBN Co's secondary data centre location.
