Urgent system update tonight including downtime, 2010-08-18, 20:00 - 24:00 CEST

Due to a planned hardware expansion (new application and storage servers) in our hosting center that is scheduled for Friday we have to urgently deploy a general system update (updated operating system packages, as well as configuration and monitoring improvements).

This will require a restart of all physical and virtual machines as the kernel will be updated.

The update will start at 20:00 CEST tonight and we're hoping to be done by 24:00 CEST. The actual downtime of individual machines is expected to be significantly less than 1 hour.

All of our services provided from the hosting centre in Oberhausen (private and shared virtual machines, mail server, internal monitoring and infrastructure) will be affected at some point during the maintenance period.

Customers with access to the Nagios monitoring infrastructure will receive notifications about the specific service and host availability.
