Planned maintenance on Orange and Purple servers

We will be upgrading the servers orange and purple over the weekend of 15-16 Feb 2014.

• Orange will be upgraded at 23:00 on Sat 15 Feb 2014* Purple will be upgraded at 23:00 on Sun 16 Feb 2014

Services will be upgraded one by one and take around 30 minutes. We will then take the opportunity to reboot these servers to load a new Kernel which will take all sites offline for around 3 minutes.
