I do consulting work from time to time, in most cases this involves helping companies creating computer games, but it's also about Website development quite often. This discussion came up yesterday:
Client: We think about using Amazon AWS for hosting, what do you think?
Me: I wouldn't do it. Amazon recently showed that they'll shut down your whole site from one minute to the next, without any warning, if they don't like you.
Client: Really?
Me: Yes, they did this with Wikileaks, just last week.
Client: You are right! So no Amazon then.
They will now use some of the many alternatives. Probably a good decision. If you are running web services, you better be reliable, I guess. Amazon also just
announced their DNS service. I think people will now think twice before using this.
