The UIUC network is back up and running after a “bug” in networking devices caused the system to become unstable this morning, said Mike Corn, director of Security Services and Information Privacy at the University.

According to a 9:40 a.m. post on the CITES Web site, network service had been interrupted, and some students found themselves unable to access on- and off-campus resources.

The outage continued for at least an hour, as a 10:53 a.m. post stated the issue had been resolved.

“These things happen once in a while,” Corn said.

While Corn said the University tries to build as much redundancy as possible into the system, it’s too expensive to ensure every component. Instead, they focus redundancy on only the critical parts.

A similar incident occured about two weeks ago when students and faculty were unable to access Compass, an online resource for class materials. Corn said that event was completely unrelated to Tuesday’s outage, and that the two interruptions occured for different reasons.
