I've been a customer of theirs for a long while and will note that their customer service is amazing. They helped implement what I needed and offer support anytime I need.
Now that S3 has matured and prices have continued to drop, though, I am going to be moving to trim costs. I actually kicked off backups to S3 earlier this month and am backing up to both S3 and rsync.net at the moment, with the plan of ending rsync once I've tested restores and made it through a billing cycle at Amazon.
Wow. To stress the amazing level of customer service, someone there just ran across my comment and reached out - noting that my pricing was set for an older structure, updating me to a far more competitive rate and offering a retroactive credit.
While Amazon has offered some great service, it's never been as good as that.
They really do stand by and provide a superior level of support and assistance if you need it on the technical side as well.
