We need to apply security patches to our web servers that run Grails and Django. Typically, we can do these with minimal or no outage. At most, we’ll have a 15-20 minute outage after 5pm on Tue 7 April 2026. All custom web applications, including ATLAS, Who-What, and Class Dashboard, will potentially be affected during this time.

Thanks for your patience as we work to keep our systems updated!
