Security update: beware of broken shared library dependencies

Today (2012-06-28) we are rolling out an unusually large security update. The update is necessary to fix known vulnerabilities. Unfortunately, the change has a small chance of breaking customer-compiled C extensions. We did our best to retain binary compatibility but we cannot guarantee it in every single case.

We ask all developers that have installed C extensions to verify that their programs are still starting up correctly. If not, a simple recompile should be sufficient to fix the problem.

Maintenance of switching infrastructure on 2012-07-05

On 2012-07-05 between 22:00pm and 23:00pm CEST we will change the power connection of one of our switches. This will cause a short interruption of network connectivity for some VMs. We expect the interruption to take less than 5 minutes.

This change is necessary to modernize the power distribution system within our racks. We try to perform this using redundant power connections without interruption of service as far as possible. During the next weeks we will also update our second rack which will require another short switch interruption. We will announce the required maintenance window separately.
