Just checked again; there's only one failure in the last 200 (#9197-9395)

9298 failed URLRequestTestHTTP.RawBodyBytesNoContentEncoding:


../../net/url_request/url_request_unittest.cc:8147: Failure
Value of: req->GetRawBodyBytes()
  Actual: 0
Expected: 5

I can't find ios-simulator in the flakiness dashboard, so I can't tell whether this is still occurring or not.
(https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=net_unittests&tests=URLRequestTestHTTP.BasicAuth only shows results for Android N5X Swarm Builder and Marshmallow 64 bit Tester)

I suspect the embedded http test server is either not started when it says it is, or it's returning empty documents rather than the expected ones.

Assigning tentatively to the eroman -- you reviewed the last patch to touch the startup code there -- can you take a look and see if there's anything there that might fail specifically on the ios simulator?

Passing off to the current network triager.

Didn't get to this (some people missed their shift so I was dealing with a backlog). Moving to triage queue properly.
Looking at the most recent 200 builds before Dec 05 16:29. I didn't see any build-failure on net_unittests. 

We might want to leave this open for a while to confirm it's not flaky.
