On this update, we will look at the progress made since our initial update.
A reminder that this quarter’s main focus is on:
* Debugging tests on interactive workers (only Linux on TaskCluster)
* Improve end to end times on Try (Thunder Try project)

#####
* Bug 1287604 - Experiment with different AWS instance types for TC
linux64 builds
* Some initial experiments have shown we can shave 20 minutes off an
average linux64 build by using more powerful AWS instances, with a
reasonable cost tradeoff. We’ll start the work of migrating to these new
instances soon.
* Bug 1272083 - Downloading and unzipping should be performed as data is
received
* Project for investigation has been started:
https://github.com/armenzg/download_and_unpack
* Bug 1286336 - Improve interaction of automation with version control
* Buildbot AMIs now seeded with mozilla-unified repo (Bug 1232442)
* TaskCluster decision and various lint/test tasks now use `hg
robustcheckout` and share caches more optimally (Bug 1247168)
* Flake8 tasks now complete in as little as 9s (~3m before)
* Decision tasks now complete in <60s on average
* Some TaskCluster tasks now share VCS checkouts on Try (Bug 1289643)
* Tasks will complete faster on Try due to not having to perform
full VCS checkout
