Routine firewall changes will be processed by the end of the next business day, although changes are often processed much sooner. Firewall changes may be expedited by calling the 24/7 IT Support Center at (520) 626-TECH (8324).
Emergency changes may be processed 24/7 by calling the Network Operations Center (NOC) at (520) 621-7999 and asking for 'Red Pager' to be paged. Emergency firewall changes are defined as those which critically impact a department's services and cannot wait until regular business hours.
Firewall services function 24/7 other than during routine maintenance windows. Please visit our Scheduled IT Maintenance Windows webpage for more information.
