The Bing Webmaster team recently received feedback that our APIs were intermittently failing, and we deeply regret any inconveniences caused from the API failures. We recognize the frustrations that this may have caused. Upon investigation, we discovered a technical glitch which led to API call failure that is now resolved. We are very grateful to you, our users, who brought this to our attention and thank you for your continued feedback and support.
