Millions of staff and students at over 150 centers of further education were left without access to their online resources following a cyber-attack on the University of London Computer Centre.

As well as blocking users from accessing Moodle, which the ULCC hosts, a number of university and education related websites were brought down, including the Universities UK website and the European Library.

Amongst the universities affected by the hack were the University of Warwick, Queen Mary University of London, Birkbeck and Manchester Metropolitan University.

A spokesperson for the ULCC, which hosts more than 3 million users, said the "whole system" was brought down between 7:30 a.m. and 11:45 a.m., resulting in a "complete shutdown."
