Ask PG: Could you, would you, add some RAM?

Earlier this year, you wrote: "Giving links longer expirations is trivially easy." Is that still true? "More" links have been breaking inside of ten minutes at peak; it'd be great to see that fixed.

Longer term, do you have any kind of reporting on how many expired link requests you get? It'd be a good way to catch problems. C'mon, HN is a critical infrastructure point now! The addicts among us need some five-nines love.
