But you are much more expensive than S3 & CloudFront when it comes to request pricing
Cloud Storage considers retrieving an object through its HTTP url is considered a class B XML request type which is priced at $0.01/10,000 ops. This is 1.3x-2.5x more expensive than cloudfront and s3 respectively. This is also not well documented and caused me some trouble. I didn't expect HTTP GET requests to be counted as XML API requests.
