We have scheduled maintenance on our Internet Simulator (NetSim) tool starting at 11:59 PM on March 5th, 2025, and continuing into the early morning of March 6th. If you actively use the Internet Simulator during this time, your students may get split between simulations, and page reloads could cause data from a previous simulation to be lost. You can reset the simulation for your classroom to fix these issues. Thank you for being so understanding as we work to improve our systems.
