Any Progress on Diagnosing “Request timed out” HttpExceptions?

Question

I am having the same issue as described in this post, Diagnosing "Request timed out" HttpExceptions. I've turned on Failed Request Tracing as recommended and am working with someone at MS (although it's painfully slow).

The original post hasn't been updated in over a year, so I'm wondering if a fix was ever found or if you're just ignoring these errors.

Any help would be appreciated.
