Yes. Shadowtunnelz Shadowsocks service is available in China.
On late October 2017, the Great Firewall of China(GFW) introduced few changes that disrupted service for some of the largest Shadowsocks and VPN services. Some of our servers were impacted by these changes as well.
We are happy to announce that our Shadowsocks service is available for our Chinese valued customers in most of our supported regions.
