    4 天前开始,出现 DNS 被抢答的情况,这几天或轻或重,一直存在着。
    如果挂全局代理,除了受地域限制的(比如在线看视频)不能访问外,所有访问是正常的。
    随便截个测试的屏:

    附 PowerShell 代码:

    # Requires PowerShell 3.0 or above
    function Test-DNSError {
        if ($count -ne 0) {
            Remove-Variable count -ErrorAction SilentlyContinue
        }
        $count++
        Write-Host -ForegroundColor Cyan "Loop $count`:"
        $direct = Resolve-DnsName 10000.gd.cn
        foreach ( $Address in $($direct.IP4Address)){
            Write-Host -ForegroundColor Red "`tDirectly resolve 10000.gd.cn`: $Address."
        }
        $withServer = Resolve-DnsName 10000.gd.cn -Server 1.1.1.1
        Write-Host -ForegroundColor Green "`tResolve 10000.gd.cn by 1.1.1.1`: $($withServer.IP4Address)."
    
        Write-Host -ForegroundColor Gray "------------------------------------------------"
        
        Start-Sleep -Seconds 30
    
        Test-DNSError
    }
