we had to upgrade some of our servers and this has made them unavailable for a short period of time.
Countries like Irland, Denmark and Sweden are offline.
France has some missing servers in Paris and Germany has some missing servers in Hamburg.
Here is a Blog post about it: https://blog.cyberghostvpn.com/servers-temporary-unavailable/
It's currently our top priority to get these servers back online, thank you for your understanding.
