Part of Revera’s datacentre at Auckland’s William Pickering Drive lost power yesterday evening during scheduled preventative UPS maintenance.
The outage occurred around 5.30pm.
A test battery fault triggered the release of suppression gas, causing a UPS shutdown, resulting in the loss of power to one datacentre suite in the facility.
Revera general manager Robin Cockayne says it was not a failure of any critical power system or backup power system, rather a battery fault that has since been remedied.
He says Revera immediately initiated a start-up sequence and restored power in less than 60 seconds. Technicians then undertook remedial activity to return affected production environments to normal service.
The majority of the affected systems were fully operational by 7pm.

The reality is outages in Data Centres occur - and the real problem is when client don't plan for - or expect - them to occur.
That's when you see significant outages caused by equipment, suppliers response (or lack of) and IT staff struggling to recover.
Plan for it, and you won't be caught out or surprised, or find yourself trying to explain why there was an outage in the first place.

1 most computer rooms /data centres with suppression gas require both heat and smoke detectors to operate before the release of gas !! so did they have a battery fire ?
2 why would you shut down a UPS on a release of gas ?
3 most racks would/should be feed from 2 independant UPS's and equipment in the racks with dual / redundant PSU so why did any equpment go down

See http://en.wikipedia.org/wiki/Data_center for a simple explanation or download the paper at http://www.uptimeinstitute.com/component/docman/doc_download/5-tiers-standard-topology for more detailed information.
From what I see there is no need for an alternative national power grid e.g. separate power feeds to a data centre, for it to be tier 4. How a data centre deals with external power failures, which are to be expected and planned for, is the question.
