   We are assessing a global software security vulnerability that may require preventative maintenance on myIGDIs, myON, DnA, Nearpod, SchoolCity, StarPhonics, and eduCLIMBER today, October 21. We want to provide advance notice to schools and districts planning to use these products. If maintenance is necessary, it may occur on short notice and could temporarily interrupt access to one or more of these products. We will share updates as we confirm which products require maintenance, including timing and expected duration when available. Thank you for your patience as we work to protect the security and reliability of our services.
