Não aguento mais - Request URL

BOa tarde,

não aguento mais ver este erro, me ajudem o que fazer?


The requested URL could not be retrieved

--------------------------------------------------------------------------------

While trying to retrieve the URL: http://www.vivo.com.br/

The following error was encountered:

Unable to determine IP address from host name for www.vivo.com.br
The dnsserver returned:

No DNS records
This means that:

The cache was not able to resolve the hostname presented in the URL.
Check if the address is correct.

Isso está dando direto, quase em todos os sites.

Obrigado

Cara, o seu servidor DNS esta configurado direitinho? ou voce esta usando um que funcione? como ta configurado a parte de dns do seu proxy?

editei o resolv.conf, coloquei 2 servidores de dns lá dentro.
Estou usando o dns do meu provedor de internet, é o dns direto do provedor.

esse é o meu squid.conf
