szga.cn 优化建议

1、针对dns解析查询在线及dns测速结果，该域名存在响应时间剧烈波动，最快仅4ms最慢达2670ms，建议利用dns测速工具持续监控并排查上海电信节点质量，优先优化平均响应并改善dns节点覆盖。
2、检测中出现两次ips为空的异常解析记录，建议启用dns污染检测工具确认是否遭受dns劫持或解析失败，同时结合dns历史解析记录查询验证dns解析记录稳定性，确保dns在线查询结果一致可靠。
3、鉴于所有有效记录均指向同一上海电信出口，建议配置智能dns或增加备用节点以降低单点依赖风险，并定期执行dns解析速度测试与dns域名查询，提升dns服务器查询的容错性及dns解析在线响应效率。
