Since the hard drive errors a month ago we have been starting to
experience more frequent SATA errors in the server logs. We believe
the motherboard is most likely responsible for this problem (we have
already replaced PSU and SATA cables).
 
We are therefore taking the decision to replace the motherboard this
coming Friday (10th July). We shall be working in the data center from
around 11pm, and will start the motherboard replacement after midnight
to minimise disruption.
 
We expect a downtime of around 20 minutes.
