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：

I’ve seen posts where students talk about planning ahead by searching for places to buy a paper or exploring options for <a href="https://www.reddit.com/r/NewtoCollege/comments/1j84uam/i_want_to_buy_an_essay_online_which/">buying term papers</a> when they anticipate a heavy workload. It’s usually more about having reference material ready when needed. Many say that being able to buy essay online gives them extra confidence before they start writing their own assignments from scratch.

A lot of students turn to academic writing services when they need reliable<a href="https://www.reddit.com/r/studypartner/comments/1k3rjht/best_dissertation_writing_services/">dissertation help</a> .

It’s becoming normal to hear students say they’ve chosen to buy essay paper or <a href="https://www.reddit.com/r/NewtoCollege/comments/1j84uam/i_want_to_buy_an_essay_online_which/">buy college papers</a> simply to understand what a strong academic essay looks like. Many find it easier to learn by examining well-written examples rather than reading guidelines alone. That might be why conversations about buying papers online keep popping up in student communities.

When deadlines hit hard, a good dissertation writing service can be a lifesaver. Many thesis writing services have expert writers who deliver quality work fast.

I’m in a pretty demanding program, and there are days where referencing a purchased sample essay feels like a lifesaver. I’ve tried <a href="https://www.reddit.com/r/NewtoCollege/comments/1j84uam/i_want_to_buy_an_essay_online_which/">buying term papers</a> before just to compare research approaches. Honestly, academic writing gets pretty overwhelming, so anything that helps you understand what your final result should look like is fair game imo.

Grad school really humbled me. There were moments where I genuinely didn’t know where to start, so I ended up checking places to <a href="https://www.reddit.com/r/NewtoCollege/comments/1j84uam/i_want_to_buy_an_essay_online_which/">buy a paper</a>r just to understand how to structure a literature review properly. I’ve also seen friends go the buying paper online route when they’re juggling work and classes. Not for submitting — just to get clarity.

I used to judge people for looking for places to buy an essay, but after juggling work and school, I get it. Sometimes you just need a reference to figure out the formatting or tone. A friend even told me they occasionally <a href="https://www.reddit.com/r/College_Pals/comments/1pc5a84/write_my_paper_for_me_best_websites/">order an essay paper</a> just to use as a guide. Reddit is full of people asking for essay writer suggestions whenever finals hit, so it’s obviously not a rare thing.

Back in my second year, I’d constantly see people online asking for essay writer suggestions or where to order an essay paper when they were overwhelmed. Meanwhile, others were more focused on things like <a href="https://www.reddit.com/r/College_Pals/comments/1pc5a84/write_my_paper_for_me_best_websites/">professional essay editing</a> because they already wrote the paper but wanted someone to polish it. Whether it’s editing or checking places to buy essay, everyone ends up looking for help at some point.
