Rob, the last time we inquired about this (to my knowledge) was one month ago (see email subject 'migrating MobileFrontend browser tests to WMF Jenkins'). We saw no substantive followup, and our browser test builds have been broken since the migration over one month ago as a result of infrastructural issues. This not only rendered the automated browser tests essentially useless for us but it has also become a significant drain on time and focus. This isn't a case of us asking 'are we there yet' - rather it's a case of us trying to understand when we'll be able to rely on our browser tests again and to see if there's any way we can help to improve the situation.
