I spaced and forgot to post this last week, so here's a double edition covering everything so far this month. I'll also be away for the next 3 Fridays, and Kim volunteered to take the reigns in my stead. Now, on with it! Major highlights:

We had a busy couple of weeks of important, but relatively boring work. We shipped 5 releases (2 betas, Firefox 30.0 & 24.6.0esr, Thunderbird 24.6.0), did a series of uplifts, and continued moving machines from scl1 to scl3.
Catlee did some investigation into our CDN bandwidth and found that on average, 20% of users who have a partial update available still end up downloading the complete update.
I finished switching B2G updates to aus4.mozilla.org. The updates should now be more reliable, and we'll be able to kill update.boot2gecko.org in the near future. Because we're abiding by standard update channel names now, this also means that the Socorro folks are able to process crashes for most B2G builds.
Mike got his patch that allows RelEng builds to be built with mach ready to land. This is the step along the path making automation steps reproducible by developers, and enabling parallelization of post-build steps.
Ed had us disable coalecing for changes that land within a few minutes of each other. During tree closures for bustage, this should help get the tree open faster because fewer builds will be needed for bisection.
