BrownSites is regularly updated to address security issues and to roll out updates.
WebServices reserves Tuesdays (6-10am) for any major changes or updates to the BrownSites core. This maintenance window is scheduled weekly, but not always used.
During the weekly maintenance window we will implement any updates that are needed and may affect more than one sites configuration or may cause a service interruption. Generally the interruptions should be brief - (a few minutes). Longer interruptions may take place during this window for major changes, such as core upgrades. The likely scenario during such changes is that there will be multiple brief outages spread across the window.
