    Padrão 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
