At around 6pm last night the University community experienced widespread network problems. These prevented students from logging into the student computing service in the IC and other computing rooms and also prevented staff and students from connecting to wired and wireless internet across campus and in residences.
These network problems can be quite complex. CiCS staff initially set to work to investigate and fix the underlying cause. Once this was rectified, additional CiCS staff were required to restore services, which began to return shortly after 8pm.
Throughout the work we kept people updated on progress via twitter and in return received lots of useful information and feedback about the effects our work was having such as when and where services were returning.
Thankfully, such widespread service outages are quite rare. We apologise to our staff and students for the loss of services last night, and in addition thank everyone who supported us through the work and passed on information that helped us diagnose and fix the problems.
