So, Amazon is announcing their fancy Amazon web services system. This is supposedly so that "developers [get] direct access to Amazon's robust technology platform."
Well, as someone who uses the Alexa traffic data on a regular basis, I can tell you one thing - Alexa is apparently running on some separate "platform" that really really sucks.
That's the problem with being a provider of "robust technology platforms" - it's really hard and almost everyone screws up every now and then. Remember media temple, they're the "we use a fancy grid of servers so that your site never goes down". Uh, right (Outages for MediaTemple Grid Hosting Service story at netcraft).
