The current servers for OAT are old and out of date. To maintain the performance and security of OAT, IT Services will be migrating OAT to new servers on 20th March 2018 and will take a full day to do the necessary work.
OAT will be taken out of service for the day whilst the work is carried out. We have tried to schedule the work for when the least number of people will be needing to use OAT but acknowledge that some people will be affected by this maintenance work. We apologise for any inconvenience caused.
