Since yesterday until now, you might have noticed that some images on this site can’t be loaded. The server on which those images reside became inaccessible because of DNS failure. But how to contact the administrator? That’s a question.
Well, thanks Google cache. I got their telephone number, QQ number, and alternative email address. The custom service girl told me that their DNS server had been recovered. But there is still a buffering time up to 24 hrs, during which DNS records should be updated.
March 10th UPDATE: not solved yet.
