    Was testing private proxies and some had this 503 error. Not sure what that error means. Sometimes the error disappears after retesting the proxy immediately

    It may be that endpoint server (which you are connecting thru proxy) is down or the proxy server is busy and refusing connections. Some proxy servers return this when the authentication(proxy username or password) is failed.

    Okay. But 503 error doesn't mean any Google ban right?

    503 errors in the HTTP cycle

    Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle when it communicates with the Web server:

    * Obtain an IP address from the IP name of the site (the site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
    * Open an IP socket connection to that IP address.
    * Write an HTTP data stream through that socket.
    * Receive an HTTP data stream back from the Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.

    Usually 503 errors are the proxies' fault because they either refuse the connection because too many people are already connected or because that proxy cannot access the website at the moment.

    But it doesn't mean you got banned.

    And you are right, most of the time this error is only temporairly and will resolve itself within some period of time.
