What about both feeds happening on the same day at the same time?

HI Damien,

My apologies that’s correct – but isn’t anyone concerned about the works being completed during business hours?

What about increased loading of the active rail once one of them is switched off for these works?

Regards

Shaun

    HI Noggers,

    Has anyone seen this scheduled maintenance notification happening
    next week?

    They maybe upgrading feeds or boards throughout the datacentre –
    has everyone seen this notification of works?

    It appears to be happening starting 5PM through to 2AM AEST for
    all Datahalls on the same date.

    *WHAT:*
    NEXTDC M1 Melbourne data centre, with the assistance of specialist
    contractors, will conduct offline preventative electrical
    maintenance work on high-voltage and low-voltage main isolators.
    This will affect A and B feeds to the racks in Data Hall 2/3/4 on
    the 15th of August.

    *WHEN:*
    A Feed - Tuesday 15th August 2017 07:00 UTC +10 until 16:00 UTC +10.
    B Feed - Tuesday 15th August 2017 07:00 UTC +10 until 16:00 UTC +10.

    *HOW AM I AFFECTED?*
    Due to the nature of the work a single feed will be removed as per
    the dates and times above. We recommend that customers balance the
    power between both power rails to minimise impact during this
    period. If you have single feed devices we recommend you:

    Regards

    Shaun
