I use Yahoo YQL to parse the next feed: https://www.thiscomplexworld.com/tag/optimization-and-analytics/feed/. The problem is that the parsing result changes randomly from time to time. Sometimes it returns status code 400, sometimes it parses this feed successfully with the same query: 2 results examples. (sorry for placing them on the same picture - I can't insert more that 2 links)
So the question is How to make it work?
Thanks in advance.
