Planned Datacentre electrical works - Cadogan House, Reading
Scheduled Maintenance Report for Pulsant Service
Completed
Please be aware of the cancellation of the previously advised planned maintenance window.

Pulsant's focus with any maintenance work we undertake is always to put customer service first, but equally consider risk mitigation.

Although Cadogan House has been unaffected, in light of the recent utility power outage incidents for Suttons Business Park on 30th November and the solution put in place by our power provider whilst they establish a more permanent fix, under our Risk Assessment and Management process we have decided to cancel the planned works until the New Year.

Due to the upcoming festive period and change freeze, the decision was made that we would be better to re-schedule these works in the New Year.
Once we have confirmation of the new revised dates we will re-submit a maintenance window when these changes will take place.

We apologise for any inconvenience caused, but maintaining a high level of customer service and risk mitigation is our priority.

A further notification will be sent out in the New Year once we have confirmation of the new proposed dates.

Update
Please be aware of the postponement of the previously planned maintenance window.

Pulsant's focus with any maintenance work which we undertake is always to put customer service first, but equally the mitigation of risk.

Although Cadogan House was unaffected, we feel that it is prudent to postpone these works due to the recent instability in the mains power grid in and around Reading on Wednesday 23rd November, and to ensure stability from the local grid.

The previously proposed works have now been rescheduled for Friday 2nd December, starting at 0800GMT and we will continue to monitor and work with 3rd party providers leading up to this date. If anything changes, we will of course sent out further notifications.

The full, updated, notification is detailed below:

---------

WHAT
In keeping with the Pulsant Datacentre plant infrastructure capacity management and efficiency programme, we will be carrying out scheduled modifications to the generator backup configuration at our Cadogan House, Reading, datacentre.

SERVICE IMPACT
None expected - This work will be carried out on only one generator feed at any one time. This work is being carried out only on emergency backup cabling and will not affect the datacentre facilities during normal operation. However, due to the nature of this work and some customers having single corded supplies to their racks, power will be deemed "At Risk" for a portion of the maintenance window.

The works will be completed by specialist 3rd parties, supervised by Pulsant datacentre management throughout. The generator functionality will be fully tested prior to being returned to normal service and complete power protection will be restored upon completion of these works.

WHY
Pulsant is revising and downgrading the generator capacity required at the Cadogan House Datacentre.

Cadogan House has four generators delivering standby power to the site. Two legacy generator sets connected to the datacentre are being removed as part of our ongoing capacity management and efficiency strategy. This work is the first of two stages of work intended to allow us to decommission these legacy generator sets and remove them from service. After the conclusion of these works, the datacentre will remain fully supported by two modern diesel generators.

WHEN
Work will commence during the following maintenance window:

Stage One
Friday 2nd December 2016, starting at 0800GMT and concluding by 1800GMT on the same day

Stage Two
Saturday 10th December 2016, starting at 0800GMT and concluding by 1800GMT on the same day

The "At Risk" window will be kept to an absolute minimum and all power backup systems will be returned to full resilience at the earliest opportunity.

A completed notification will be sent out once the works have been completed and normal service has resumed.

If you have any questions, please raise a ticket by emailing support@pulsant.com or by calling our support team directly.
