x/website: redirect wrongly to golang.google.cn

[xxchan]

I was reading go blog:

https://blog.golang.org/context

Yesterday, it redirects https://golang.google.cn/context and shows:

Similarly, report a website issue (https://golang.google.cn/issues/new?title=x/website:) redirects to https://golang.google.cn/issues/new?title=x/website: and show similar error.

And yesterday I found go.dev and blog https://go.dev/blog/context, it didn't redirect.
But today it also redirects to https://golang.google.cn/blog/context
