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：

So helpful! I’ve definitely been there, Googling ‘best dissertation writing services’ at 2 a.m. In a panic. <a href="https://www.reddit.com/r/studypartner/comments/1k3rjht/best_dissertation_writing_services/">Dissertation help</a> saved me when I had a paper due in 12 hours and no time to write it. Was the best decision and I don't regret it at all.

There's a lot a human editor can do to improve and polish a piece that AIs like grammarly can't, That's why you need a <a href="https://www.reddit.com/r/College_Pals/comments/1pc5hze/write_my_essay_recommendations_and_reviews_needed/">profe... essay editor</a>. AI will only tell you when something is technically wrong, and make fairly formulaic suggestions about 'clarity' which can make your writing quite repetitive. A human can look to improve the flow, the readability, the structure, and the natural style of English if you're not a native speaker.

I've thought about writing research papers for people for a long time. I'm a <a href="https://www.reddit.com/r/College_Pals/comments/1peokru/best_research_paper_writing_services/">paper writer</a> , so becoming an ""instant expert"" on a topic and then writing about it comes easily to me. How did you get started doing this kind of work? How is the money? Do you think it would be worthwhile for me to do part-time? I already work from home, and I often find myself with downtime.

I used an <a href="https://www.reddit.com/r/College_Pals/comments/1pc5hze/write_my_essay_recommendations_and_reviews_needed/">essay writing service</a> for a complex essay last semester, and I was honestly impressed with the outcome. The writer followed my instructions to the letter, and they even included more references than I had expected. The paper was well-researched and delivered on time. If you're looking for reliable help, you should definitely check them out!

Sounds like you’re in the final stretch, congrats on that! I’ve used a few <a href="https://www.reddit.com/r/studypartner/comments/1k3rjht/best_dissertation_writing_services/">dissertation help</a> services for my papers, especially when aiming for top-tier results. For proofreading and overall quality. They helped me tighten up my papers, make sure everything’s polished, and avoid any awkward phrasing. I’d say if Grammarly has reached its limit, a more personalized service like that could be a solid choice for your review paper.

I've placed a couple of orders on my favorite <a href="https://www.reddit.com/r/studypartner/comments/1k3rjht/best_dissertation_writing_services/">academic writing service</a> and I gotta say, the results always exceeded my expectations because I never have to make any changes to the content of the papers. I definitely enjoy working together with the writers as they are always polite & follow my instructions pretty meticulously.

I’ve tried research paper writing service before, and I can confirm it’s one of the best research writing services for students on a tight deadline. Their writers are knowledgeable, and the customer support is super responsive. I ordered a research paper, and they followed my instructions to the letter, delivering it on time. If you're looking for a <a href="https://www.reddit.com/r/College_Pals/comments/1peokru/best_research_paper_writing_services/"> paper writer</a> who is reliable and delivers quality work, they’re worth considering.

I totally get why you’re cautious about these online services, some are good while some aren't. From experience, having a <a href="https://www.reddit.com/r/College\_Pals/comments/1pc5hze/write\_my\_essay\_recommendations\_and\_reviews\_needed/">professional essay editor</a> is way better than dealing with these hit-or-miss platforms. I had one for my undergrad and even my post-grad projects, and it was next level. Personal writers win, all the time!
