Update: The update has been completed and evertyhing went according to plan. Thus, the service interruption has been concluded.
OVPN will have a planned service interruption that affects all VPN servers on September 28th, between 03:00 and 03:30.
The cause of the interruption is that OpenSSL has released new updates.
The service interruption will be very short per server since we only need to restart the OpenVPN processes after the update. We will update this blog post when the service interruption has been completed.
