I am not a Heroku customer and maybe there is more substance to his complaints but I didn't see anything in the post that would cause him to want to leave his hosting provider with guns blazing like this. Reduce their prices because their service providers have reduced their rates? Seriously which company you know does that? Do we even know what arrangement Heroku has with amazon? Isn't it possible that as a large customer their rates are already discounted. On the subject of downtime he didn't actually say that his application was down as a result of the maintenance in this instance or any other.
