This looks like a duplicate of [Throttle violation after 300 calls][1] but this one is reported as fixed in 2012. Today I made ~450 requests with an app key (no oauth token) and suddenly got a 502 response: > throttle_violation : too many requests from this IP, more requests available in 86281 seconds" Did I do something wrong? The same API key used to work some weeks ago and I made several thousand requests per day without getting any errors.
