Scheduled Maintenance
Dear Customer,

Please be aware of the following planned maintenance window for UPS Maintenance at our Maidenhead Facility, Pulsant 2/3 only.

WHAT
In keeping with the manufacturer's recommendations and the Pulsant planned and preventative maintenance regime, we will be carrying out scheduled UPS maintenance at our Maidenhead Facility, Pulsant 2/3 only.

SERVICE IMPACT
NONE -There will be no planned service impact, this is an advisory note, as there will be reduced UPS resilience whilst the maintenance is being carried out.
Power will remain unaffected to customer racks, but with reduced resiliency during the maintenance period.
However to bring the unit(s) back on line there will be an element of switching that needs to be done hence an "At Risk" notification is being sent out.
The maintenance will be completed by a specialist 3rd party and the UPS units will be fully tested prior to being returned to normal service. Complete power protection will be restored upon completion of the UPS maintenance.

WHY
Pulsant follow a stringent Planned Preventative Maintenance regime. This work forms a major part of this regime and the firmware update ensures full availability and continued functionality of the units in line with the manufacturers recommendations.
Pulsant's specialist UPS contractors will be on site to complete the scheduled maintenance, supervised by the datacentre management team throughout.

WHEN
Work has been scheduled to be carried out during the following maintenance window:
Tuesday 5th of December 2017, commencing at 22:00 GMT and ending by 06:00 GMT on Wednesday December 6th 2017.
The "At Risk" window will be kept to an absolute minimum and the UPS 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.

Dear Customer,

Please be aware of the following planned maintenance window for essential Maintenance on our Branch Circuit Monitoring System at our South London facility, Data Hall 1 only.


WHAT
In line with the manufacturers recommendations and following our stringent Planned Preventative Maintenance regime we are planning to undertake maintenance and servicing on our BCM system on site.

SERVICE IMPACT
NONE - There will be no planned service impact.
However it will be necessary to remove the front panel of each Distribution Board to undertake a physical check and undertake maintenance of the per-circuit monitoring.
These works will involve checking physical connections and confirming readings and applying any associated updates.
Whilst this panel is being removed and the checking of circuits, there is a low risk of a potential trip of individual breakers, hence an At Risk notification being sent out to inform our customers accordingly.

Only one distribution board will be worked on at any one time and all works are being carried out by a specialist contractor but overseen by the Data Centre team throughout. RAMS have been submitted and approved and planned to mitigate risk as far as practicable.

WHY
This inspection, maintenance and servicing of the power monitoring system forms an important part of our maintenance regime and ensures that the system is both working correctly, but also an opportunity to check the hardware and complete any remedial works as necessary including any updates.

WHEN
Work is scheduled to be carried out during the following maintenance window:

A FEED Supply Boards: - Saturday 4th November through to Sunday 5th November 2017.
B FEED Supply Boards: - Saturday 9th December through to Sunday 10th December 2017.
The maintenance window will be between 09:00GMT and 17:00GMT each day

A completed notification will be sent out once the works have been completed and normal service has resumed for each day.
If you have any questions, please raise a ticket by emailing support@pulsant.com or by calling our support team directly.

Scheduled - Dear Customer,

Following on from our POSTPONED broadcast sent out on the Friday 29TH October. Please be aware of the following confirmed re-scheduled essential maintenance being carried out at our South London Facility.

WHAT
As part of Pulsants planned maintenance regime, it is necessary for us to undertake an Annual Darken Building Test on site, to ensure all infrastructure works correctly in the event of a full loss of mains power. In parallel with this we are working with our HV contractor and undertaking the annual Inspection of our Transformers and Ring Main Units on site, so that we minimise impact and risk to the business and our customer base.

SERVICE IMPACT
NONE - No interruption or disruption to service is expected during these essential works, however due to the level of switching that will be undertaken during executing our Darken Building Test procedure, we are issuing a courtesy At Risk notification to all our customers.

WHY
The Annual Darken Building Test forms part of our stringent maintenance regime and this is to ensure all infrastructure works correctly in the event of a full loss of mains power to site.
To do this we will be working with our 3rd party contractors and the electricity company to isolate the mains power to the site and perform essential testing of our HV and LV infrastructure.
During this period, it will be necessary to run the site on generators. Pulsant will follow our Darken Building Test procedure, which will isolate each of the incoming utility supplies to site. In parallel with this the Transformers and Ring Main Units will also be inspected and serviced.
The testing will be completed by Pulsant staff and a number of specialised 3rd party contractors.
All diesel supplies to the site have been checked and confirmed adequate supplies, reserve supplies are on standby. Once works have been completed, the fuel supplies will be replenished accordingly.
We have provisioned a maintenance window of up to 8 hours to allow us an adequate time window to complete all the necessary tests. All personnel will remain on-site during this maintenance window and for a period of up to 1-hour post the maintenance being completed window.
Works are expected to be non-service affecting as customers will remain on UPS protected supplies whilst the Generators take up the load on one feed (the other will remain unaffected) and then remain on Generator load (in an N+1 configuration) until all testing has been completed. This maintenance does involve changes to power source to the site, hence an At Risk notification is being sent out.
Pulsant has been preparing extensively for this scheduled Darken Building Test.

We will have a number of different contractors and Pulsant personnel on site including expert contractors to support our Generators, UPS devices, electrical infrastructure and most importantly Pulsant network and site support staff. We have worked with the electricity utility supplier to mitigate risk as far as possible, below is the planned approach with regards to completing all necessary works and undertaking this Annual Darken Building Test

WHEN
To mitigate risk and impact, Pulsant have scheduled for these works to be carried out at the weekend.
Pulsant confirm that the maintenance window is noted below and the associated At Risk period:
Saturday 18th of November 2017, commencing at 10.00 GMT and completed by Saturday 18th of November 2017 by 18.00 GMT.
The At Risk window will be kept to an absolute minimum and the site will have utility mains power restored and resuming full site protection at the earliest opportunity.
Please accept our sincere apologies for any inconvenience this may cause.

Nov 9, 22:00 GMT
Scheduled - What:
Pulsant have been advised by the vendor to reload a core router to resolve a problem with routing metrovlan traffic.

At this time, we have a workaround in place whereby traffic is already re-routing through alternate paths. However during the reload, there will be a brief period of no more than 15 minutes where connectivity will have reduced resilience.

Maintenance activities carry a minimal degree of risk which is why we announce these works to our customers with as much warning as possible. Our intention is to complete the maintenance with no impact to customers.
