*What is happening?* On Wednesday, October 30, 2019, from 5 a.m. - 5:30 a.m., US:IT Staff will be performing maintenance on the UMS Single Sign-On system. The actual downtime during the maintenance window is expected to be less than 5 minutes, with the remainder of the time being reserved for testing and verification to ensure that the change is successful. During this work, there may be issues logging into Blackboard, GMail, MaineStreet, MyCampus Portal, Box, Zoom, and other services that utilize the UMS Single Sign-On service. Existing sessions to applications should not be disrupted. If you receive an error message, you should wait a few minutes and try your request again. *Why is it necessary?* Service monitoring has indicated that our Single Sign-On systems are utilizing more memory than normal and we are seeing additional errors in the system logs. The issues do not appear to be impacting service at this point, but to ensure service stability, we are going to make a few adjustments and restart the UMS Single Sign-On services during this service maintenance window. If you experience any issues with the UMS Single Sign-On system after this maintenace, please contact IT Support Services at 800.696.4357, via the Service Desk web form, or by email: [log in to unmask] Steve. -- Steven Premeau, Director of Enterprise Systems Architecture & Administration University Services: Information Technology University of Maine System | (207) 581-5836 (desk) | (207) 944-9391 (mobile)
