slightly adventurous, but not entirely unreasonable (mostly in terms of if something goes bad in both, staff get stretched thin remediating issues).<o:p></o:p></p>

<p>HI Noggers,<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>Has anyone seen this scheduled maintenance notification happening next week?<o:p></o:p></p>
<p>They maybe upgrading feeds or boards throughout the datacentre – has everyone seen this notification of works?<o:p></o:p></p>
<p>It appears to be happening starting 5PM through to 2AM AEST for all Datahalls on the same date.<o:p></o:p></p>

<p><b>WHAT:</b><br>
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.<br>
<br>
<b>WHEN:</b><br>
A Feed - Tuesday 15th August 2017 07:00 UTC +10 until 16:00 UTC +10.<br>
B Feed - Tuesday 15th August 2017 07:00 UTC +10 until 16:00 UTC +10.<br>
<br>
<b>HOW AM I AFFECTED?</b><br>
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:<o:p></o:p></p>
