今年是 DDNS（动态域名）的多事之秋。5月初最早最出名的 DDNS 服务商 DynDNS 中止免费服务，所有服务项目开始收费。我在想，DynDNS 自信过了头，凭什么用户要交钱而不是直接离开 DynDNS？！

总之，我是选择离开 DynDNS 改投 No-IP 的环抱。

经过几个月观察，No-IP 还是很稳定的，直到今天，No-IP 塌了半边天。今天，我的IPPBX监控程序不停在提醒我，我家的 IP 地址和 No-IP DDNS 解析出来的 IP 不一致，这通常是在路由器掉线重拨，IP 地址刚发生改变才会收到的邮件，我不停收到几百封这样邮件，我还以为是宽带出问题了，直到吃晚饭时，收到 No-IP 发来的一封邮件：

We want to update all our loyal customers about the service outages that many of you are experiencing today. This is NOT A TECHINCAL ISSUE WITH NO-IP.
This morning, Microsoft served a federal court order and seized 22 of our most commonly used domains because they claimed that some of the subdomains have been abused by creators of malware. We were very surprised by this. We have a long history of proactively working with other companies when cases of alleged malicious activity have been reported to us. Unfortunately, Microsoft never contacted us or asked us to block any subdomains, even though we have an open line of communication with Microsoft corporate executives.

We have been in contact with Microsoft today. They claim that their intent is to only filter out the known bad hostnames in each seized domain, while continuing to allow the good hostnames to resolve. However, this is not happening. Apparently, the Microsoft infrastructure is not able to handle the billions of queries from our customers. Millions of innocent users are experiencing outages to their services because of Microsoft’s attempt to remediate hostnames associated with a few bad actors.

Had Microsoft contacted us, we could and would have taken immediate action. Microsoft now claims that it just wants to get us to clean up our act, but its draconian actions have affected millions of innocent Internet users.

回家一测，果然是 noip.me 不解析任何子域名了。我在上面有三个子域名，全部中了躺枪。我赶紧按照 No-IP 的提示，将 DDNS 换用还未中枪的 onthewifi.com 子域名来解析。

我只是没想通，No-IP 的域名怎么归着微软管？但这个事件说明：为了域名的健康，远离微软。小庆幸一下：我奉行的“尽量不用微软产品”的方针大致是正确的。
