Susano ? And if him , who do I not need on this team ? <| sep |> Could have been a problem with their DNS or a problem with a proxy server . Basically they didn ' t configure it properly to only allow certain requests through . You can get a variety of proxy software , some free some paid for but usually by default they will forward any request to any site and need to be configured to restrict access to certain domains . For example a company might have a proxy setup so you can access internal servers remotely but might have forgot to only allow requests to those servers so if this is the case you could connect and browse any website you wanted and it wouldn ' t be blocked , whereas if you tried and access was restricted you ' d just get an error page .
