Regular maintenance must be performed on IT systems to ensure they are operating efficiently and securely. Many of these maintenance procedures require operating efficiently and securely interruption for the duration of the procedure. Systems include services such as software applications, servers, voice, video and data communications, local area networks (LAN), wide area networks (WAN), wireless networking (WLAN), internet and ORION. Campus locations include:

  • The main University campus (1280 Main St. W)
  • One James North (1 James N)
  • David Braley Health Sciences Centre (100 Main St. W)
  • Ron Joyce Centre (4350 South Service Rd, Burlington)

Due to the size, complexity and integration of McMaster’s IT systems, UTS is identifying a monthly maintenance window for the year so you may better plan your activities in advance.

Standardized Maintenance Windows

UTS has established the following standardized maintenance windows for repairs, installations, upgrades, testing, patches and other processes and procedures which may cause limited or no access to IT system resources. During the scheduled maintenance window, you may experience anything from slow response, limited access, to no connectivity; or you may experience no interruption whatsoever.

While not every maintenance window may be utilized, it is important to set aside the time and encourage the campus community to plan accordingly.

Maintenance is restricted to “Emergency Only” during the following times:

  • Exam windows during the fall and winter terms.
  • Enrolment dates during the summer.
  • Week before and first week of classes for fall and winter terms.
  • Planned maintenance activities will be announced on the UTS Service Dashboard page. An email distribution to the McMaster community will be sent when a planned maintenance activity may cause a significant outage or occur/extend past the normal maintenance window. 
  • There may be occasions during an emergency or time-critical event where notification may be made after the maintenance procedure has been completed. 
  • Emergency and time-critical maintenance or repairs may be performed outside of the normal maintenance windows and performed with minimal or no prior notifications. Post-event notifications will be sent. 
  • Off-campus providers (such as internet or telecommunications providers) may have different maintenance schedules which are outside the control of UTS. 
  • Localized outages, with agreement of local building administrators, may occur outside of the normal maintenance windows
