Sydney-based data centre provider, Global Switch, has traced a power incident which affected some customers back to a unnamed contractor who accidentally initiated a fire trip system shutdown on one of its uninterruptible power supply (UPS) groups.
This meant one out of two power distribution feeds stopped working at approximately 10:20AM AEST on 14 July.
Global Switch managing director, Damon Reid, told Computerworld Australia that this incident lead to a "very small" number of customers losing power.
"The power was reestablished on to the second feed for those customers within an hour and the UPS system was back up and running on that second feed as well," Reid said. "We know the root cause of the problem now and we're just working through how that occurred."
Reid also said that findings from the investigative report, which was to be completed over the next few days, would be released to affected customers. "We will keep our customers fully up to date as we work through this," he said.
Telecommunications service provider, Pacnet, confirmed that its network was affected by the power failure on level two at the Global Switch data centre.
Pacnet Australia chief executive officer, Deborah Homewood, said in a statement that it experienced a "network event." "While the core network was not affected, some edge services were impacted. Pacnet maintained continued communication with affected customers and managed a higher than normal call volume during this time," she said.
All services had now been restored to normal operation but the company was "monitoring the situation," Homewood said.
In a statement supplied by Pacnet, George Pezzutto of telecommunication service provider AINS (a Pacnet customer), claimed that not all customers were affected by the event.
“We had a number of carrier interconnects go down that ultimately affected our network but we had no issue whatsoever with Pacnet," said Pezzutto.
"They stayed up because we both had dual power feeds to our equipment,” he said.
