I have just been advised that on the 7th of February the server which the forum is hosted on will be having upgrades.
Possible of a few short outages during this time.
Date: Tuesday 7th February 2012
Time: 10:00pm - 11:59pm (GMT +11)
This upgrade is expected to take approximately 45 minutes to 1 hour, during this time you may see one or two short 'outages' on your website lasting 1-2 minutes as the new PHP engine is brought online.
