Comment 1 Ryan Haddad 2017-11-16 09:00:09 PST 
One of the earliest failures on the dashboard points to https://trac.webkit.org/changeset/224857/webkit, but it is flaky.
Comment 2 Ryan Haddad 2017-11-16 11:13:49 PST 
The failures are limited to Mac-wk2 bots.
Comment 3 youenn fablet 2017-11-16 11:17:17 PST 
We are not supporting fetch controller so we could skip this test for now
Comment 4 Ryan Haddad 2017-11-16 16:53:05 PST 
Marked test as flaky in https://trac.webkit.org/changeset/224946/webkit
