Sorry for network interruption in some regions for about two days

Hi,

Recently, some of our visitors could not visit our site and we are aware of this issue. If you visit from places other than Mainland China, you might be unable to visit our site due to DNS probe issues. We have monitored and tried to fix in the past two days and there should be no problems in DNS probing.

Again, we are sorry this long interruption.
