      <br>
      The main issue with Google's DNS / OpenDNS is the fact that Akamai
      still doesn't play nicely with it.  Most other CDN's are fine, but
      Akamai being one of the largest does make it a problem.  It's most
      noticeable when downloading software updates (eg iTunes / OSX
      etc), as it doesn't correctly choose an Australian peer. For large
      updates I'll change my DNS before and then change it back to
      8.8.8.8 afterwards. Other than this, using Google's DNS works
      perfectly.<br>
      <br>
      Thanks,<br>
      <br>
      Tim.<br>

            <p class="MsoNormal">As an FYI, Telstra's DNS is notoriously
              slow when updating. I recently conducted a change for a
              customer we moved from dual ADSL to Single SHDSL and
              updated the DNS entries.<o:p></o:p></p>

              Telstra was the last to update despite having the TTL
              dropped as low as it could could go. This because the root
              TLDN server within Telstra only updates EVERY 24HRS and no
              sooner/later. Telstra ignore TTLs.<o:p></o:p></p>
