UTS: weekend monthly maintenance schedule for January to December 2021
University Technology Services (UTS) has established standardized maintenance windows for repairs, installations, upgrades, testing, patches, and other processes and procedures, which may cause limited or interrupted access to McMaster’s IT system resources.
Maintenance is scheduled over a weekend once per month. During these scheduled maintenance windows, users may experience anything from slow response, limited access, or no connectivity; or may experience no interruption whatsoever.
Scheduled Mosaic maintenance will start no earlier than end of business on Friday (5:00 p.m.) and will be completed no later than Monday morning (8:00 a.m.). Mosaic updates could impact services provided via the Mosaic platform. Information on potential outages will be posted directly to Mosaic Alerts.
Scheduled Systems and Network maintenance will be performed on Sunday between 6:00 a.m. and 12:00 p.m. Network maintenance could impact 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.
UTS will notify the campus community of anticipated impacts and timing in advance of scheduled maintenance windows. Please note that these windows are subject to change in order to accommodate University activities.
