Extended Maintenance Schedule

decorative image

OneIT maintains over 600 systems and services which need to be regularly patched and upgraded; most of this works is routine with minimum impact. However, sometimes the work is complicated, requires extended time and may include a significant outage. OneIT partnered with university administration to identify the best windows when this extended maintenance could happen; please see the schedule below.

We will aim to begin maintenance at 5 p.m. on the first day and end by 5 p.m. on the last day. Detailed information wil be posted below, on the system status page, and in Niner Insider approximately 1 month in advance.

For IT help, submit a ticket at help.charlotte.edu or call 7-5500.
