Amazon's limit is about 10k requests per 24 hours, and there are people snarfing those up pretty quick. -----Original Message----- From: google-appengine@googlegroups.com [mailto:google-appeng...@googlegroups.com] On Behalf Of dalenewman Sent: Friday, September 04, 2009 8:38 AM To: Google App Engine Subject: [google-appengine] Amazon Product Advertising API - HTTP 503 (Throttle) Responses 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. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
