Many but not all Kansas University buildings were back online Wednesday morning, following Tuesday’s campuswide Internet outage.

Work continued throughout the day to fully restore Internet service to others, but a few buildings were expected to remain offline possibly through Thursday, according to KU Information Technology.

Late Wednesday afternoon Internet was still down at Jayhawker Towers apartments, the engineering complex and Green Hall, which houses the law school, according to KU Information Technology. Snow Hall had only partial connectivity.

Connectivity was expected to be restored at all buildings by Friday morning, according to a KU IT update late Wednesday.

“We are working to repair the severely damaged cables and restore network and connectivity as soon as possible to all remaining buildings,” KU Chief Information officer Bob Lim said in an email message Wednesday. “I appreciate your patience as we continue working to fully restore services to all customers and buildings on campus.”

Housing facilities still lacked Internet service Wednesday morning, but connectivity was restored to all but Jayhawker Towers by midday, according to a KU IT update. Baehr Audio-Reader and Hilltop Childcare Facility also lacked Internet most of the morning but had it restored by midday.

The outage, reported about 1:30 p.m. Tuesday, was blamed on a major fiber cable cut. KU IT officials declined to say exactly where or how the fibers got cut.

The outage also temporarily froze state testing mid-test for thousands of K-12 students across 17 states — including Kansas and Alaska — that rely on the KU-based Center for Educational Testing and Evaluation to administer the online tests.
