This notice is issued in partnership with our Data Centre Provider in the UK. Our data centre partner are performing some preventative maintenance tonight and details are below. Not all our servers are affected but emails are being sent to all affected clients now.
Last week we had two short bursts of downtime on a three of our servers located in one cabinet. As most servers were completely unaffected you may not have been aware of this issue but here is the link for more information:

In simple terms a power breaker in the final leg to the cabinet failed causing a power trip in that cabinet only. Please note at no point did the data centre lose power and this issue happened in the final leg past the UPS and Generators and only affected one cabinet. On Tuesday we added some additional power redundancy to that cabinet by installing this device:
"Olson Electronics 32A Automatic Transfer Switches"

This notice is to let you know we will be carrying out some emergency preventative maintenance tonight at 10pm in our UK data centre.
We will be installing ‘Automatic Transfer Switches’ in our other cabinets to prevent the same issue happening in future with any other server. This is being done to provide a double source of power feed from 2 different distribution panels in the facility. This way in the future if there is any issue with any of the power source from the A side it will automatically flow to the B side. Like wise if there is any issue with the B side it will flow through the A side. These breakers are very rare to fail and in our entire history we have never seen one fail like the one in the other cabinet did last Friday. So this is a very rare case.
This will be completed on:
Friday Sept 21 2012 at 22:00 hours local UK time
Downtime expected: 1 Hour Max
All servers will be properly shut down, we will then feed the A + B side of the ATS and then boot everything back up. The whole process will take less than 1 hour.
Please let us know if you have any questions by opening a helpdesk ticket.
