We have a planned service maintenance with very short notice between 03:00 and 03:05 at 22/10/2014. This is because we need to update OpenSSL on our servers to defend against POODLE.
All SQL and web servers have been updated previously, but since our servers run Debian 8 it has taken a bit longer to get a patch that fixes the issue. An update has now been released that fixes the issue, which makes updating the VPN servers possible.
The update was successful and went according to plan.
