A cyber-attack on the academic computer network known as Janet has led to students across the UK not being able to submit their work.
Distributed denial of service (DDoS) attacks began on Monday and are continuing, according to the network’s operator, Jisc. Its statement says it is using “various blocks and filtering” to limit the impact of the disruption, “but the details of each attack are subject to change”.
One of the universities effected the University of Manchester said staff and students had experienced intermittent problems accessing external sites. Emails to staff and students warned them to expect “slow performance or a complete lack of access to external services”.
