Overview
This document defines the service level agreement for Networks for Departments.
Service description
ITS assists departments, colleges, and university organizations with designing, installing, maintaining, and managing reliable, secure, high-volume, standards-based wireless and wired networks. During major and minor building renovations and new construction projects, ITS regularly consults with departments to ensure that networks are robust, reliable, efficient, and adhere to standards and recommendations.
Intended users
Networks for Departments can be used by UT departments, colleges, and university organizations.
Supported computing environment
The Campus Network presently supports IEEE Ethernet (mostly 10/100/1000Base-T, ask about other standards) and TCP/IP version 4.
Technical support
Tier 1 technical support is available during help desk hours. Tier 2 during normal business hours. Routine requests are typically addressed within one business day.
Tier 1
End users should start with Tier 1 technical support. Any user can call the ITS Help Desk at 512-475-9400. Users with a departmental Technical Support Contact (TSC) should contact that individual.
Tier 2
Departmental support staff and the ITS Help Desk may escalate issues to Tier 2. The ITS Help Desk and operators may escalate building-wide outages after hours to on-call Tier 2 support personnel.
Maintenance
ITS will notify customers about both scheduled and unscheduled maintenance using the ITS Services Status page of service availability and service delivery issues. Services may not be available during the maintenance periods.
Scheduled maintenance
Regularly scheduled campus-wide maintenance occurs Sunday mornings from 8 to 11 a.m., during or close to semester inter-sessions (fall, winter, summer). This campus-wide maintenance is scheduled and announced five months in advance. To the maximum extent possible, installation of service, application, and security updates will be performed these times. Additional non-campus-wide maintenance is scheduled with departmental representatives.
Unscheduled maintenance
Unscheduled maintenance tasks that require service downtime will be announced as soon as possible on the ITS Services Status page.
Change notification
ITS will notify customers using the ITS Services Status page of service availability and service delivery issues for Networks for Departments.
For specific building point-of-presence (POP) maintenance, ITS will notify local building IT support personnel and rely on them to notify their building occupants.
User responsibilities
Subscribers (users) of the service and identified owners/administrators agree to be aware of and adhere to the university's Acceptable Use Policy.
Networks for Departments subscribers agree to:
- Contact their local IT support staff to report network problems. If they do not know who their local support staff are, they should contact the ITS Help Desk.
