Login and OOD node access restricted due to serious security issue - No ETA

**Due to a serious in-the-wild exploit which can compromise Fedora-based Linux distributions including Rocky, which is used on the cluster, we need to restrict access. All login and OOD nodes are shut down until a fix can be put in place. Jobs running on the cluster will continue running.****No ETA, There is not fix at this time. We will update our status page in the morning once we have more information or a fix to roll out.****This is a serious exploit and we do not take this measure lightly. Please follow this status page for updates and eventual resolution.**

We are developing a plan of attack to mitigate this exploit. Please know that this is a very serious issue and so we are treating it as such. Thank you for your understanding. We are currently awaiting further information from the Redhat/Fedora/Rocky community but building a plan in the meantime with the information we have. More details to follow as we can share them. If you need to access storage (except scratch and home directories), [Globus ](https://docs.rc.fas.harvard.edu/kb/globus-file-transfer/)is still online and available. But again, login nodes and OOD are not available.

To mitigate this exploit we will need to restart -all nodes- on the cluster. This **will begin at 1PM** and run until all nodes have restarted (no ETA). This **will mean** any un-finished jobs will be **terminated**. There is no way to avoid this. We will then be validating the fix before re-opening the login. OOD nodes, and scheduler.Next steps and updates will be posted here.
