DNS和“站点离线”消息 [英] DNS and "site is offline" messages

问题描述

情况是这样的：假设有一个Web服务器，无论什么原因停止工作。我有可能使用DNS让另一台服务器回复网页，并显示类似site is offline？的消息。感谢您的所有帮助！

The scenario is this: suppose there is a web server that for whatever reason has stopped working. Is it possible for me to use DNS to have another server respond with a webpage with a message similar to "site is offline?" Thanks in advance for all of your help!

推荐答案

是的。您只需要将第二台服务器启动并运行，然后将DNS条目更改为指向新服务器的新A记录。 （或者如果您有IPv6也可以使用AAAA记录）。

Yes. You simply need to get the second server up and running, and then change the DNS entries to point to the new A record for the new server. (Or AAAA record if you have IPv6 for it as well).
