@SciGuySpace What's the reason the illustration imagines the towers in pairs of two. Why not all of them spaced out at similar intervals.

@nateberkopec Are there circumstances where you manually delete unnecessary keys from the cache? As updated_at values change, and stale versions of keys stick around until finally being evicted, I imagine that 50%+ of our 24GB of Memcached memory is just for holding stale keys.
