Downtime on Zombiemod Server and Voice server

Anyone hosted on our CBJ5 game/voice server will experience interruptions for the good part of today:

Dear Customer,

Please be informed that there will be a scheduled power maintenance and upgrade activities in CBJ5 Data Centre. This will commence on:

Second Power Source Feed
Date                                                                           : 10th October 2009
Time                                                                           : 12:00 am – 8:00 pm
Estimated Power Downtime Duration                             : 18 hours

The purpose of this maintenance is for CSF to carry out preventive maintenance on our data centre electrical system which is required by the Electricity Supply Act 1990. According the Electricity Supply Act 1990 (ACT 447) and Electricity Supply (Successor Company) Act 1990 (Act 448) under clause 110 (4) states:

“Any protective relay and device of an installation, shall be checked, tested and calibrated by a competent person at least once in every two years, or at any time as directed by the Commission”.

To test and calibrate the protective devices, CSF need to remove them from the switchboards which will cause disruption of power. Since there are two power sources feeding our data centre, CSF are going to do the test and calibration on one power source at a time. There will be one source of power feeding our data centre at all times. This exercise will allow CSF to ensure all protective devices are in proper working order to prevent damages to IT equipments.

Every customer’s rack is supplied with 2 power sources with each supply coming from different PDU. Our PDUs receive each power source feed alternately. So when we shutdown one PDU the other power supply from the other PDU is still available so if you use both power sources simultaneously on one equipment, the redundant power prevents your equipment from losing power.
There will be a NO downtime occurs during the exercise if you are using simultaneously both power supplies provided to each of your rack.

If your equipment has only one power module hence using one power source feed only or it has 2 power modules but connected to the same power source feed, it will experience downtime. In order to minimize downtime to single power module equipment you will have to plug in the equipment power cable to the available power source feed when one power source feed is down.

We strongly advise customers to do necessary backup of their critical data.

For further information and clarification on the maintenance or if you experience difficulties after the maintenance period, please contact us via email at idc@netmyne.com, or call SOC at 03-2274 3515 or contact your respective account executive.

We apologize in advance for any inconvenience caused.
