Hydra security shutdown

We have shut down access to Hydra: both the login nodes and the portal are not accessible until further notice.

A serious security flaw in the Linux kernel is being actively exploited. We have no indication that the security of the cluster has been compromised; this shutdown is out of caution.

We are working on upgrading all our systems to fix the flaw. As soon as this is done, the cluster will be available again. If all goes well, the systems should be back up at the beginning of next week.

You can still access your data through Globus.
