I'm not sure if this is a temporary issue that's already being worked on (e.g. https://twitter.com/bradfitz/status/892055083092815874 aka #21237), or an unrelated legitimate issue. I'll report it so it can be triaged.

The following URL:

https://golang.org/cl/47352

Redirects to:

https://go-review.googlesource.com/c/gddo/%20/47352/

Which appears as a blank white page:

Happens whether I'm logged in or in incognito window. I tried clearing all cache.

On the other hand, modifying the URL to:

https://go-review.googlesource.com/c/47352/

It works okay:

This seems to affect all CLs, not just gddo ones, as far as I can tell. E.g., https://golang.org/cl/50990 (main repo CL) and https://golang.org/cl/43812 (x/tools CL) are affected too.

I don't know if the issue is that the first URL should work, but doesn't, or that the golang.org/cl redirect should point to second URL directly. /cc @bradfitz
