exmed.cn 优化建议

1、dns测速在线显示绝大多数节点响应在14至70毫秒，建议用dns解析查询在线定期核查阿里云解析一致性，结合dns测速工具与dns检测工具锁定1241毫秒异常节点，并借助dns污染查询排查dns劫持检测风险。
2、dns在线测试表明单节点集中承载全部解析，建议通过dns记录查询、dns历史解析记录查询与dns解析记录查询配置多线路智能dns，参考杭州移动dns、上海dns等常用dns做dns选优，提升dns解析速度测试表现。
3、针对个别超时无返回，建议使用dns在线检测、dns检测与dns查询网持续监控，结合dns速度在线测试和在线dns测试工具建立告警，关注dns服务器查询与dns生效检测，降低dns污染在线检测暴露的解析中断风险。
