7img.cn 优化建议

1、解析记录单一指向上海腾讯节点，存在单点故障风险，建议启用域名dns负载均衡或dns轮询机制，分散请求至多节点，提升dns在线查询服务的可用性，避免因单IP故障导致dns劫持检测或dns污染检测功能中断。
2、整体响应时间表现稳定，但存在1124ms和733ms的极端延迟峰值，建议优先使用dns测速工具定位慢速节点，并参考dns在线测试结果优化本地dns解析配置，可切换至阿里公共dns或百度dns等公共服务，缩短dns记录查询的响应时长。
3、针对高延迟场景，建议结合dns污染检测工具和dns速度在线测试数据，定期执行dns解析记录查询并评估dns地址查询结果，为不同网络环境预设dns解析在线优选策略，尤其是在上海移动dns或上海联通dns环境下，提升dns测试的覆盖准确度。
