As part of our data centre’s ongoing work to increase network resilience, they are splitting the data centre up into a number of discrete zones, each running an entirely separate network. To achieve this, they need to move some of our servers from one rack to another. We have therefore scheduled a maintenance window when the affected servers will be shut down, moved to another rack, and started back up.
Each of the servers below will be powered off and restarted. The expected downtime duration will be 30 minutes which will occur between 22:00 and 00:00 on 12/10/2011 (UK Time).
The following servers are relevant to this message:
Database Server: mysql.controldns.co.uk (mySQL4)
Database Server: mysql5.controldns.co.uk (mySQL5)
Database Server: mysql5-7.controldns.co.uk (mySQL5)
Backup Mail Server: mx1.backupmailserver.co.uk
Web Server: Qbic07
Web Server: Qbic09
Web Server: Qbic11
Please accept our apologies for any inconvenience this planned maintenance causes and rest assured we will do everything we can to keep the downtime to a minimum.
Update: This maintenance was completed by 22:40 without incident. Each server was only offline for approximately 10 minutes and everything is now running as normal.
