-2 error code and no response headers for Google Analytics

[aroben]

http://www.webpagetest.org/result/140616...1/details/ has a 99999 result, which I understand means that there was an error with one or more requests. Looking at the requests on the page, I see that https://www.google-analytics.com/analytics.js and the corresponding beacon image that it loads both have an error code of -2, and have no response headers at all.

I've looked at the wpthook code, and see that -2 is the default error code for every response. Since there are no response headers for these requests, it seems the -2 code is the final code for these responses.

Any idea why this is happening, or what I can do to fix it? Having an overall 99999 result is interfering with some automation I've built around WebPagetest. I can update the automation, but I'd like to better understand what's going on first.
