I had to make some changes to improve server stability. But it means everyone needs a new openvpn account. I’ve emailed everyone updated login details for openvpn. If you didn’t receive yours, let me know.
The previous instability was caused by automated server updates and reboots, followed by the server not rebooting properly. Also the openvpn accounts had too many users at the same time, but now everyone has their own account. Server overloading can still happen but it is unlikely provided everyone remembers to log off when they’ve finished.
