3月21日，一场突如其来的DDos攻击让我的博客瞬间陷入了风雨飘摇的境地。那一天，阿里云CDN的防御粒度设置得相对较小，原本我以为这样的设置足以抵挡任何潜在的威胁。然而，现实却给我上了一堂深刻的课。攻击仅仅持续了一分钟，就因阿里云CDN的熔断机制而迅速被遏制。面对如此迅猛的攻击，我毫不犹豫地选择了关闭网站，暂时让它在黑暗中躲避风雨。

夜幕降临，我原以为这场风波已经平息，于是怀着忐忑的心情重新开启了网站。然而，命运似乎并不打算放过我。第二天中午，博客再次遭受了更为猛烈的攻击。短时间内，流量飙升到了惊人的48G，请求次数更是高达260万。我不禁感叹，这次攻击的力量远超我的想象。好在阿里云CDN的熔断机制再次发挥了作用，将攻击的影响控制在了极短的时间内。两次攻击加起来仅仅持续了2分钟，却产生了高达60G的流量和300万的请求次数。

回首这次事件，我深感庆幸。幸好听从了店长的建议，将流量峰值调整到了合适的位置：50Mbps。正是这个明智的决策，让我在攻击面前有了更多的缓冲空间，避免了可能造成的更大损失。同时，我也深刻认识到了网络安全的重要性。在数字化时代，网络安全已经成为我们生活中不可或缺的一部分。只有时刻保持警惕，加强防范措施，才能确保我们的数字世界安全无虞。

此外，我也想提醒各位朋友们，在遭受攻击时千万不要抱有侥幸心理。关闭域名解析和源站是应对攻击的必要手段，可以有效防止CDN和源站的流量同时被刷爆。同时，我们也应该保持冷静和理智，不要试图通过一些不切实际的方式来解决问题。将域名解析到类似gov.cn的域名上，期望国家能帮忙抵挡攻击的做法，不仅不现实，还可能给自己带来不必要的麻烦和损失。


以下是这次攻击的ip，需要的人可以将其添加到自己的CDN黑名单中
