University IT have now resolved an IT service interruption that affected staff and students within the School of Psychology between approximately 16:00 on 25 February and 11:30 on 26 February. During this period, access to several University IT services, including email, was unavailable. Emails sent to affected staff and students, both from within and outside the University, would not have been delivered. Unfortunately, these undelivered messages cannot be identified or retrieved. In these cases, the sender will have received an “undeliverable” notification.If you were expecting an email during this time window, we recommend contacting the sender to request that the message be resent. We sincerely apologise for the disruption this caused. University IT has reviewed the incident and is implementing measures to prevent a similar occurrence in future. Thank you for your understanding.
