One of the hard disks drives that contain 'H: drive' was suffering from failures and consequently, alternative space was found for the data. To ensure minimal data loss, two thirds of H: drive users had their H: drive made 'read-only' whilst repairs to H: drive were undertaken. The action taken to repair H: drive was successful and all systems are now back to full working order. Further information for full details.

Problems today for some users on campus who were unable to access the Internet or display Message of the Day. The problem was cleared by 11:40 after identifying a rogue departmental (i.e. non-ISS) system that was mal-configured. This system has been disconnected from the campus network until further notice. There were ongoing problems for serveral PC users later in the day.
