Subject: Hetzner Online Client Information: Please check the CPU load of your server!
Date: Tue, 03 Jul 2012 14:59:03 +0200

Dear ,

During the night of 30.06.2012 to 01.07.2012 our internal 
monitoring systems registered an increase in the level of
IT power usage by approximately one megawatt.

The reason for this huge surge is the additional switched 
leap second which can lead to permanent CPU load on Linux 
servers.

According to heise.de, various Linux distributions are 
affected by this. Further information can be found at:

In order to reduce CPU load to a normal level again, a 
restart of the whole system is necessary in many cases. 
First, a soft reboot via the command line should be 
attempted. Failing that, you have the option of performing 
a hardware reset via the Robot administration interface. 
For this, select menu item "Server" and the "Reset" tab
for the respective server in the administration interface.

Please do not hesitate to contact us, should you have any 
queries.

Kind regards,
