Security Shutdown - Login Disabled
Published: 8 Jul 2026
by
NEMO2 Team
Multiple security vulnerabilities currently exist for which exploit code is already available. To prevent misuse, we are forced to shut down login access.
Jobs that are already running will not be terminated and continue to run as normal. The cluster itself keeps running; only login is not possible until the security issues have been resolved.
We hope to restore login access by Friday, July 17th.
If you have any questions, please contact the NEMO2 team.
