Hi,
due to a recently disclosed vulnerability in glibc, we will be rebooting the Feide production servers between 10:00 and 12:00 today. We are not aware of any applications on the login servers that are vulnerable to the issue, but to be certain the servers will be rebooted.
Since the servers will be rebooted one-by-one, the reboots will not directly affect user logins. However, because all Feide session data is stored in-memory, user who have logged in before we the reboot will lose their single-signon session and must enter their username and password the next time they access the Feide login page.
For more information about the vulnerability, see the following article at Ars Technica:
