Dear ACCESS Community, The telephony credits available in the ACCESS DUO account unexpectedly ran out the evening of November 13, 2025. Those employing phone-call-based authentication for DUO have been getting denied by DUO as a result. We are working as quickly as possible to purchase additional credits to resolve this issue, but due to university purchasing policies there may be a delay before the credits become available. We regret the inconvenience of this sudden suspension of phone-call-based DUO authentication and direct all affected members of the community to select one of the several alternative methods of DUO authentication described at https://guide.duo.com/ (https://6fax6u7ab.cc.rs6.net/tn.jsp?f=0013UWUxb0WeMD2uTMupnTB5qASFg_xjuvzRv6psbGE-sHyF1oKWQHpPQPMXpJQTcmCsz4DD0QMrM_Zr_-CuaS16vi7zC0LbABPDsWRaN5qEDYmxKVBPwE-rPE1kySrVmUydiFBxNXlBNEAXRlH6OjmcA==&c=10ka7qroOSdY1qz0BlkWJMDU9CFOeZlw2SrKzSFTMJhvlleLJztGtg==&ch=U2-7NbP4COXJ3gs0XcWUE4Sc_viAYFAi2FOggUXfAc3nNQT82t1-RQ==). More than 90% of ACCESS community members already employ Duo Push (https://guide.duo.com/universal-prompt#duo-push) or a Platform Authenticator (e.g., passkey), and we strongly recommend that those currently configured for phone-call-based DUO authentication switch to one of these better methods. If you need assistance to update your DUO authentication method, please open a ticket at https://support.access-ci.org/help-ticket and select "I need help logging into ACCESS website" as the ticket type. We anticipate a surge in help desk tickets to help those affected, and we appreciate your patience as we work to help you as soon as we can. Regards, ACCESS Cybersecurity Team

During this maintenance we will reconfigure the Slurm scheduler to remove some nodes that were moved to a different cluster. We have a reservation in place to prevent jobs from running during this maintenance. The "squeue" output will show "ReqNodeNotAvail, Reserved for maintenance" for jobs that do not fit in the time period before the maintenance begins. These jobs will run after we release the maintenance reservation. Thanks SDSC User Services Staff
