According to treeherder's intermittent failures view, bug 1490978 has failed about 402 times between Oct 1 2018 and January 10, 2019. The failure rate seems approximately constant over that period (25-35 failures per week). The IF bot has changed the whiteboard status several times back and forth between [stockwell needswork:owner] and [stockwell unknown] (current status).
Why is this bug not being resolved?
Should the IF bot have marked it disabled-recommended?
Why did the IF bot set [stockwell unknown] a couple of times?
Why is the triage owner not responding?
Why did several attempts to find a regression range fail? (And did those delay or confuse efforts to resolve the failures?)
Let's use this as a case study to see if the IF bot rules can be improved and whether policy changes would improve outcomes.
