如何确定 Microsoft 符号服务器是否可用?如果不可用，如何与他们联系?

How to find out if the Microsoft symbol server is available? And if it's not available, how to contact them?

推荐答案

如您所见，服务器本身是可用的.它以 HTTP 404 代码响应.

As you can see, the server itself is available. It's responding with a HTTP 404 code.

您可以通过访问根页面或pingme.txt 文件.对于后者，请注意您将不会在浏览器中看到任何内容，因为它是一个 0 字节的文件.

You can check the availability by visiting the root page or the pingme.txt file on Microsoft's server. For the latter, note that you won't see anything in the browser, because it's a 0 byte file.

如果没有找到符号，服务器很慢甚至没有响应，我看到联系微软的愿望.官方电子邮件地址是 [e-mail].另一种选择是发推文 Andy Luhrs.他可能会在下一个工作日(总部位于美国)查看它，因此您将不得不等待一周结束.

If symbols are not found, the server is slow or even not responding, I see the wish of contacting Microsoft. The official email address is [e-mail]. Another option is to tweet Andy Luhrs. He'll probably have a look at it the next working day (US based), so you'll have to wait over week ends.

有些人潜伏在 SO 上，他们与 Microsoft 有直接联系，例如Sasha Goldshtein、Brian Rasmussen、Steve Johnson 和其他人.我想这些会注意到中断并在需要时通知 Microsoft.我还希望 Microsoft 员工自己使用符号服务器，因此他们可能会在您报告之前注意到这一点.

There are people lurking around here on SO who have direct contact to Microsoft, e.g. Sasha Goldshtein, Brian Rasmussen, Steve Johnson and others. I guess these will notice an outage and inform Microsoft if needed. I also expect that Microsoft employees are using the symbol server themselves, so they'll probably notice that before you could report it.
