Hi,

I'm running www.bookdope.com on GAE and I've started getting tons of
HTTP 503 responses from Amazon's Product Advertising API.  The HTTP
503 is an error response you get when you've violated the 1 request
per second per IP address rule.

I'm wondering if my application might be sharing an IP address with
another GAE application that's making requests to the Amazon Product
Advertising API and therefore increasing the likelihood of our
combined requests violating the 1 request per second rule.

I cache all my amazon responses (if they return a HTTP status code of
200) for efficiency and also to keep my Amazon requests down.

I was wondering if anyone else out there is experiencing this?  Or, if
someone from Google could confirm my suspicions.  This influx of HTTP
503's is really cramping my style - I rely on it for searching,
browsing, and book information.

Thanks,

Dale

PS: I've also posted on the Amazon Developer's forum for Product
Advertising API to see if I can get any help there.
