AECOM IT is planning to perform upgrades to the web application environment to meet our global standard. The maintenance is planned at the Denver Data Center on Saturday, February 13 and February 20 from 12:00 p.m. to 5:00 p.m. PST. During this time, there is relatively a low risk for OneSource to be unavailable.
