It’s on Craigslist’s side. This happens every few months. It’ll take a few days but their feeds will return to normal as they always do. I personally have a few CL feeds that I watch and have seen this happen half a dozen times before. I don’t know what is going on on their end but it looks like they are rate-limiting NewsBlur. I could put in some of my own rate limits to CL feeds, but I don’t think anybody wants that.
