It appears that Twitter is currently down for most users – I was first unable to access the site around 3am Eastern time. As of the time of this post, 8:30am Eastern time, I am still unable to access Twitter.com. The Twitter status site notes, “Currently experiencing elevated error rates — You may experience some problems loading twitter.com and with Twitter clients. We are aware of the problem and are taking action.”
Based on some searches on Google, it does appear that some people are able to post messages — it does look like if you use a third-party client (Seesmic, HooterSuite, TweetDeck) you might still be able to get in.
This is the first time for an extended Twitter outage in quite a long time. In the old days of Twitter outages, we would all hop on the bus to Friendfeed but that is no longer an option since many have left that service.
If you are a social media ninja, social media rockstar and are really upset or need someone to talk to because of this outage, please call 867-5309.
As always, please report in if Twitter is down for you – include your location, whether you use a client tool or the main Twitter.com site and what you are doing to occupy your time during this outage.
Of course, the outage gives me a chance to share Twitter Come Back one more time!
分布式拒绝服务攻击，亦称作洪水攻击，通常简称为DDoS或DoS（即英语“Distributed Denial of Service”的缩写）。顾名思义，即是利用网络上已被攻陷的电脑作为“丧尸”，向某一特定的目标电脑发动密集式的“拒绝服务”要求，用以把目标电脑的网络资源及系统资源耗尽，使之无法向真正正常请求的用户提供服务。黑客通过将一个个“丧尸”或者称为“肉鸡”组成丧尸网络（即Botnet），就可以发动大规模DDoS或SYN洪水网络攻击，或者将“丧尸”们组到一起进行带有利益的刷网站流量、Email垃圾邮件群发，瘫痪预定目标受雇攻击竞争对手等商业活动。
