Got an odd one....
Our Tauranga office has Telstra DSL...all sites working fine except anything to do with Google.
www.google.co.nz via our Webmarshal gives :
Access to this file has been denied because it violated a content rule.
File download (BIN, 5 bytes) was restricted by the content rule 'Block - Dangerous files'.
Turn off Webmarshal and get blank pages.
Google working at all other offices fine with no problems.
Edit : Oh, can ping google.co.nz fine
