As for redirects, our browser reached this domain in two steps. The first redirect led to /VL/trang-chu/, then it was forwarded to /default.aspx?tabid=704, and finally we managed to open this domain. We strongly recommend that the redirects should be reduced, as the more redirects a site has, the slower it loads.

IP address uses IP address which is currently shared with 3 other domains. The more sites share the same IP address, the higher the host server’s workload is. It is strongly recommended that the host server should be changed or the hosting provider should be requested to give a different (separate) IP address for this domain.
