Our internal testing with ipv6 is complete and we have worked out any bugs that we have found. Now ipv6 is fully functional, including ipv6 rdns control from SolusVM (by default SolusVM is broken in this regard, we implemented our own change to SolusVM to make this work).
We are ready to offer ipv6 for testing to our customers. If you are interested, please contact us by opening a support ticket and we will add an ipv6 address to your VPS. We do not recommend that you use ipv6 for critical production traffic yet.. Most of our upstreams do not yet offer ipv6 transit, so our ipv6 connectivity will be worse than our ipv4 connectivity and comes without SLA.
