Dear all, We are a research team from Tsinghua University and ZGC Lab. We are conducting a survey on the current deployment and usage of Looking Glass (LG) servers. Our research aims to improve the user experience as well as prevent abuse of LG. If you manage a LG server in your network and you haven’t already participated in the survey, please take a moment to participate, as we would really appreciate your valuable input. It will only take a few minutes: https://forms.gle/VDmueB2QzoZFnCyC9 Thank you! Best, Lancheng
