How is the speed from international large bandwidth to mainland China?
Large bandwidth servers use international BGP routing (PCCW/NTT/Cogent), directly connected to Hong Kong local exchanges. Speed to mainland is good during daytime and off-peak hours. During peak hours (20:00-23:00), latency and packet loss will be higher than CN2 due to international gateway congestion. If your core audience is only in mainland China with latency sensitivity, choose CN2 GIA servers.
