GitHub's new Git storage architecture

I'd have thought so from the headline + initial content but then they say that the horizontal scale techniques are basically carrying over from the existing architecture (where it seems the problem is?) and this is mostly to help with what they call "vertical scale" (intra-repo scalability). They also admit right after that the most active repos today will receive short bursts of at most dozens of writes.

So this seems like really useful planning for a near future that likely helps prevent more issues but isn't really meant to help current issues. Am I reading this right?

Of course improvements like this are always useful either way. Not dunking here at all.

Hope it helps improve reliability, it was getting hard to defend GitHub with all the recent outages.
