due to a severe kernel vulnerability (https://access.redhat.com/security/vulnerabilities/2706661) I need to reboot the stat1002, stat1003 and stat1004 hosts to install the new kernel. The reboots are scheduled for 9 AM CEST tomorrow (Oct 21st), please follow up with me or anybody in the Analytics team if you have ongoing work that can't be stopped.

The Analytics Hadoop and Kafka clusters will be rebooted too during the next hours. Event if this maintenance shouldn't cause any major issue, you might experience some service degradation. More up to date information on IRC in the analytics and operations channels.

Thanks and apologies in advance for the trouble!

Luca
