About China Golden Shield Project
Also referred to as the Great firewall of China (GFW), this is a surveillance project operated by the Ministry of Public Security of China.
We sometimes have customers in China reporting that they have difficulties accessing emails and websites that are hosted at our server in Singapore. However, there are no problems with our server and there are no similar reports from others.
So often, it can be a temporary connection issue caused by GFW. More information can be found here.
