Due to stability issues and a non functional secondary we have installed a working secondary that's completely under our control.
If you have DHCP (automatic configuration) set you don't need to worry about this.
If you have static settings, the primary server stays the same but the secondary changed. This particularly affects those who use Samba on Linux / FreeBSD etc.
Primary: 146.231.128.57
Secondary: 146.231.48.34
This setting will probably be changed in the next few months. to a more permanent address.
