Code review comment for lp://staging/~joetalbott/uci-engine/split_infra_failures

I like this, and have a dumb question about it because I haven't had a chance to try it for myself yet. If you run a ticket through with this and get an infrastructure failure, is this enough so that it actually shows up in the ticket completion status to the user as "error" rather than "failure"? If so, even better, but I wonder if as a later task we should actually explain the difference on the UI somehow. +1 from m e
