RESTORED: Network Performance Issues
Jan. 9, 2013 - As of 4:30 a.m., network service has been fully restored.
Recap of event: At approximately 2:45 p.m. on Jan. 8, the University lost connectivity to our two primary research networks and two of our three Internet service providers due to a major communications cable getting cut in downtown Chicago, which also affected Argonne and several other universities in Illinois. As a result people may have seen a brief disruption as connections failed over, followed by slow performance for off-campus connections because of reduced bandwidth. The provider was able to repair the cable and restore full service by 4:30 a.m. Jan. 9.
