[AusNOG] NextDC Melbourne - Scheduled Power Maintenance -, 15th August

[Jared Hirst]

I don’t buy it.

HV lines / boards / STS’s are worked on live all the time.

Infact Equinix had maintenance this morning I believe or over this weekend on the A1 power and there was no disruptions.

The issue I had was the way that it was ‘law’ to actually do this, not the OHS part.

Someone should tell that to these guys about the OHS part ;) imagine that Job!

Hi I did post the following link to the list the other day.

http://www.ohsrep.org.au/faqs/ohs-reps-@-work-electrical-safety-/electrical-equipment-what-are-the-lawsguidelines but this could also just be a NextDC OH&S policy as well,  as regulation from government in the tech space can be interesting as they are not always up to date with stuff.

Hey Chad,

That's a pretty general site you're pointing to.

Could you possibly be a bit more specific? Clicked through a couple of links on it but everything was very high level.

As I noted elsewhere I am in SA but my employer is national so keeping across all this is never a bad thing.

Cheers,

Sam

It comes under the Victorian Occupational Health and safety Act 2004 from the bit of reading I did yesterday.

Mark,

Totally agree. I would just like to know what law Simon was referring too?

As someone who has run colo facilities before:

It should be made completely clear during customer onboarding that the facility operator can temporarily shut down a power feed at any time. Advance warning should be desirable but optional.

If there is risk involved in doing that, it’s your job to mitigate it. The facility operator doesn’t know which bits of equipment in your tenancy are critical, and they’ve already told you to dual-feed where possible and use a rack-mount ATS for single-corded equipment.

Power work should be done during business hours, because it’s almost impossible to get emergency support or source replacement equipment out of hours.

If it isn’t safe to take a power feed offline during business hours, then you (the customer) have a design problem to solve.

They won't just disconnect both feeds at once because that would be stupid and if the entire DC was offline for too much time then that would put the owners in a rather awkward situation legally, as after say 8 or 10 hours of downtime it wouldn't be good for the owners lets put it that way.

> Also for anything that is really really mission critical you should have it hosted in multiple datacentres anyway so if something stupid does happen that you can't control you at least still have services online as the load balanced services would just switch.
