 Subject: [dns-operations] NXDomain response in Brazil network

 Hi folks,

 Anyone here has ISP contacts in Brazil like Vivo or Claro? An important
 domain *.aliyuncs.com receiving NXDomain response in the Brazil network.

 WHEN I DIG @177.159.101.225 (AS18881 TELEFÔNICA BRASIL S.A)  :

 root at localhost:~# dig @177.159.101.225 aliyuncs.com

 No error found when I dig + trace. It seems resolvers in Brazil block this
 name.
