slashdot效应

今天在wikipedia上找到了slashdot effect词条


The Slashdot effect is the term given to the phenomenon of a popular website linking to a smaller site, causing the smaller site to slow down or even temporarily close due to the increased traffic. The name comes from the huge influx of web traffic that often results from sites being mentioned on Slashdot, a popular technology news and information site. Typically, less robust sites are unable to cope with the huge increase in traffic and become unavailable – either their bandwidth is consumed or their servers fail to cope with the high number of requests.
Links from other popular websites can cause problems comparable to the Slashdot effect – see traffic overload.

如果有人在slashdot.org提交了一篇含有指向你网站链接的文章,那完了 你网站所在的服务器会因为访问量立刻激增而立刻会被slashdotted掉。看看下图


可以看到,流量瞬间猛增到将近1M每秒,cft~

已经有无数的服务器被迫down掉,就连Sun公司的服务器也难逃一劫, 下图就是
Sun Microsystems's Secure Global Desktop页面被slashdotted掉后的样子。



国内的slashdot--solidot.org的影响力还很小,solidot现象还没有这么恐怖,solidot有几篇帖子包含有本站的链接,访问量几次都“缓慢”升到了1000个ip,还有2000个PV,还好没有被solidotted掉, thank god...
