cfd-sjtu.cn 优化建议

1、建议重点开展dns解析查询在线与dns测速在线测试，当前30次检测均返回杭州阿里云节点，dns解析记录查询稳定无异常，可强化dns在线查询工具入口建设，覆盖dns污染检测与dns劫持检测场景。
2、针对dns速度在线测试结果，响应时间波动明显（18-592ms），建议引入dns测速工具进行dns选优分析，结合杭州电信dns与杭州移动dns实际表现，优化dns解析速度测试策略并配置dns轮询提升可靠性。
3、鉴于单IP架构存在dns延迟测试峰值风险，建议通过dns历史解析记录查询补充多节点对比，使用dns测试网站持续监控dns服务器查询性能，同时整合dns检测工具实现dns污染查询预警，确保dns解析查询服务高可用。
