Maintenance will be performed on the Argonne MobilePASS+ (or "Cryptocard") server from 9:30 a.m. to 10:00 a.m. (CT) on Monday, October 16. During this time, existing connections will not be interrupted, but users will not be able to establish new SSH sessions to any ALCF resource (including Globus, Aurora, Sunspot, and the AI Testbed). Attempts to authenticate during this period could result in your MobilePass+ token getting out of sync, or blocking of your IP address by Argonne's security systems. Please contact support@alcf.anl.gov with any questions or concerns.
