2008年12月11日16:21~16:26,百度的网通服务挂了。网通机房的两个F5 BIG-IP虚拟IP:202.108.22.5、202.108.22.43全部无法访问。16:27左右恢复正常。
下面是我写的一个“CDN智能DNS解析分析工具”,可以列出各类用户访问 www.baidu.com 被解析到的服务器IP地址(可以看出百度主站的IDC全在北京,前段时间还有一个北京长城宽带的多线IDC,现在去掉了),当时直接访问百度电信机房的两个虚拟IP是能打开的:

When I started my master’s program, I underestimated how complex a thesis could be. That’s when I decided to look for a <a href="https://www.reddit.com/r/studypartner/comments/1lb5zog/best_thesis_writing_service/">reliable thesis writing service</a> to help lighten the load. The support I received made the entire process less stressful. They helped refine my research questions, organize my arguments, and ensure my citations were accurate. If you ever feel stuck, getting professional thesis help can save both your time and sanity.

I’ve always struggled with tight deadlines, and last semester I decided to try a <a href="https://www.reddit.com/r/afraidtoask/comments/1mi15iq/best_services_to_write_my_paper/">professional service to write my paper for me</a>. Honestly, the experience was a lifesaver. The writer understood my topic, followed the guidelines, and delivered on time. If you’ve ever thought, “I wish someone could write my paper for me,” I can tell you it’s worth it when you find the right service. The stress reduction alone is priceless.
