MOLE hardware upgrade

This morning the work on MOLE that required the system to be taken offline was completed successfully.

We moved MOLE onto new hardware with updated operating systems and new load balancer (the bit of the system that spreads the users round the servers). A number of small changes were also made to the database server. This should provide a more resilient/expandable environment for the servers - with a more rapid start up time - which enables subsequent changes/upgrades to MOLE be made more swiftly. It also gives us easier monitoring and diagnostic information to help in resolving issues.

On Friday morning, the second period of downtime we announced on Monday will allow us to upgrade the database, and other upgrades are being planned at the moment that will will announce shortly.
