If Amazon sent a communique every time one of their services went out you'd have more email from Amazon than spam. Perhaps that's an exaggeration but there's a reason why Amazon as well as any company with an online presence (e.g. Netflix, Spotify, eBay, Wells Fargo, Facebook, CNN) will never announce outages. I believe that reason is why announce to the world how poorly they're doing in keeping their services up? Only when the outage is reported by media will they make a statement. And usually that statement is something about a server update that broke and that they are fixing it.
