Announcement
Who is affected: 
Users of our hosting services, AlternD (Aegir) and AlternC (self-managed hosting).

We have to install a security patch on our servers. This operation requires a reboot of the servers. This will happen today, June 22, between 5 and 6 pm. Effect: - AlternD: a downtime of about 5 minutes. - AlternC: a downtime of about 15 minutes.
Why: 
We have to install an important security patch to the Linux Kernel.

This patch resolves potentially serious vulnerabilities to the Linux Kernel, our servers and our overall service. Therefore, we regretfully won't be able to accomodate requests to postpone the operation.
