On Monday, August 24th the GL Linux login servers (gl.umbc.edu) will be undergoing system upgrades from 7am to 9am. The upgrades will be conducted in a rolling fashion, so at least one server will be up during this time in order to minimize the service interruption. Because we are rolling the servers through, it is important that you connect to gl.umbc.edu instead of trying to connect directly to an individual server. You can read a little more about the upgrade in the release notes:
