i have recently updated my SEP (350)MAC CLIENTS TO 12.1.7061.6600 version
after that we experimented that a lot of were trying to reach stats.qalabs.symantec.com domain but this domain name could not resolved by any DNS server(internal nor External,,, example http://network-tools.com/),this domain name no longer exists,we resolved the problem create a static Cname pointing to another symantec IP ADDRESS, it would be good if non existents domain names were removed from your aplications and documentation.
this is my symantec number Case Caso # 11322206 (stats.qalabs.symantec.com)
