Windows Live Messenger blocks www.youtube.com (Update) Everything back to normal Windows Live Messenger的座www.youtube.com （更新）一切恢复正常。
Not too long ago, users on the不久以前，用户对 Neowin.net forums neowin.net论坛 started complaining about开始抱怨 not being able to send YouTube links无法发送的YouTube链接 to their contacts on Windows Live Messenger.给他们的联络人对Windows Live Messenger的。 I was skeptic at first, but it didn’t take me very long to confirm that is indeed the case.我怀疑在第一，但它没有考虑我很长的证实，确实如此。
As you can see, any messages that contain in text or links to “www.youtube.com” fails to be delivered.你可以看到，任何邮件包含在文字或链接“ www.youtube.com ”未能交付。
Curious as a cat, I loaded up a network packet sniffer to find out exactly what’s going on behind the scenes.好奇，作为一个猫，我装了一个网络数据包嗅探器，找出到底是怎么回事幕后。 Technically, the message packets are in fact sent to the Messenger servers (so it’s not being blocked at your client), but the server sends back a negative acknowledgment (NAK) packet instead of an acknowledgment (ACK) packet.从技术上来说，信息数据包是在事实上，发送到Messenger的服务器（因此它不是被拦截在您的客户端） ，但服务器发送回的负面承认（洛）数据包，而是一个承认（的ACK ）封包。 Simply speaking, the server is refusing the message.简单来说，服务器是拒绝的讯息。
As some people may recall, in 2006 there was a正如有些人可能还记得，在2006年有一个 report quoting MSN Sweden admitting报告引述的MSN瑞典承认 Microsoft is “censoring” messages it deems a security threat.微软是“审查”的讯息它认为是安全威胁。 How it does this is by matching messages with a known list of text strings which are commonly found in phishing and malware sites such as “download.php”.它如何，这是否是由匹配的信息与已知的名单上的文字字串，这是常见的在钓鱼式攻击和恶意软件的网站，如“ download.php ” 。 Microsoft doesn’t publishes which strings are on this list for obvious reasons, but a comprehensive list of Microsoft不出版，其中字符串在这个清单上出于明显的原因，但一个全面的名单 known blocked strings can be found here众所周知，封锁字符串可以在这里找到 . 。
We all love a good conspiracy, but I don’t think anyone at Microsoft was dumb enough to do this deliberately to undermine Google.我们都爱一个良好的阴谋，但我不认为任何人在微软是哑巴不够为此蓄意破坏的Google 。 On the other hand, even if it was an accident, how do you ever trust this system?在另一方面，即使这是一个意外，你怎么以往任何时候都相信这个制度呢？
