DNS slow

Hello!

My connection decrease speed after change my DNS to Verisign Public DNS if compared with Google DNS and OpenDNS (I test Verisign DNS vs OpenDNS vs Google DNS). My location is Brazil. I observe that is necessary a optimization of your service public DNS to more speed.

Sorry for my english!

Best Regards,
Thiago

    DNS: 64.6.64.6 and 64.6.65.6

    I always note a speed smaller with Verisign Public DNS.
