I know there's a great thread somewhere here (though I can't find it in a hurry) with all AWS IP ranges listed just so people can ax accesses from AWS at firewall level.
I wanted to start doing just that but noticed access from some crawler called "kraken-crawler/0.2.0; +http://www.kontera.com/kraken-crawler.html" ( comes from 220.127.116.11 and 18.104.22.168) I don't want to say that they are legitimate - I don't know that - but I had dealt with Kontera before and, although I no longer do, it got me thinking that there may possibly be some good traffic coming from AWS. This may be helpful in deciding whether to kill all of the AWS ranges or do it more selectively.
I've requested information from Kontera on that particular crawler and will definitely update here when they respond, but I also wanted to see if other people know of any examples of good traffic from AWS? Please post the IPs and user agents if you know any good ones. Thanks!
