jssysy.cn 优化建议

1、当前解析全部指向同一江苏南通电信节点，建议利用dns解析查询工具确认是否存在dns轮询或多节点调度，结合dns速度测试分析各区域访问差异，并参考dns查询网站优化解析策略，确保dns检测结果稳定。
2、查询时间波动明显且存在高延迟，建议通过dns测速在线对比公网dns与当前dns解析速度，排查dns解析在线性能瓶颈，并借助dns检测工具验证dns污染情况，改善dns解析记录查询体验。
3、基于当前dns测速数据，建议部署智能dns或启用dns选优机制，针对江苏电信dns及周边区域选择低延迟节点，利用在线dns测试工具持续监控dns查询响应，保障dns解析查询和dns速度在线测试的可靠性。
