No, i’m not sure that in same, i bought on different providers, and i think in different data centers around the world.

And even if all of RP will be in one lan, it will be impossible to mitigate 2GByte/s attack.
but when we don’t have centralized cache, we just need to deploy more RP.

probably i found solution, i changed this function

/**
                 * Purge the URL, if 'feed' then purge related feed page also.
                 * Used in the external script to purge the homepage.
                 *
                 * @param $url
                 * @param $feed
                 * @return unknown_type
                 */
                function purgeUrl($url, $feed = true) {
                        $serverList=array("257.257.257.257","257.257.257.258","257.257.257.259");
                        foreach ($serverList as $ip ) {
                                $this->log( "- [".$ip."] Purging URL | ".$url );

                                $parse          = parse_url($url);

                                $_url_purge = $parse['scheme'].'://'.$ip.'/purge'.$parse['path'];
                                if ( $parse['query'] ) {
                                        $_url_purge .= '?'.$parse['query'];
                                }

                                $this->_do_remote_get( $_url_purge );

                                if ($feed) {
                                        $feed_string = (substr($parse['path'], -1) != '/') ? "/feed/" : "feed/";
                                        $this->_do_remote_get($parse['scheme'].'://'.$ip.'/purge'.$parse['path'].$feed_string);
                                }
                        }

                }
