The Computer Systems Lab will be undergoing planned storage upgrades starting Wednesday, June 4, 12 PM with expected completion by Tuesday, June 10, 4 PM (last day of school) that will significantly increase the speed of CSL systems. During this time, some services, including Director, JupyterHub, cluster, and TJ email may be unavailable. Ion should not be affected. Please plan ahead for possible service disruptions. If you have important data stored on the cluster, we recommend backing up that data to your own computer in the rare event data loss occurs. For questions or concerns, email sysadmins@tjhsst.edu before June 4, or csl.tjhsst@gmail.com starting June 4 (in case TJ email is down).
