yo'av, I know this isnt Zaraz related but it is somewhat related to Cloudflare Analytics and I know that you are looking into making improvements to that area of CF. We have been encountering some issues very recently on our Google Merchant Center and Google Search console intermittently marking pages as "website down"/5xx error Unfortunately Google gives very little information as to what is going on. I was able to identify that Google had encountered a 503 error which was interesting. When I started looking into the Analytics in Cloudflare I encountered the attached image which is obviously concerning. I pulled everything about the request apart, assuming that something had gone wrong with our application servers or our AWS load balancers which was causing nearly 1% of our page requests to return a 503 It was only after working through this for a few hours that I remembered that I had tweaked some settings in Cloudflare on Monday and looked into whether they could have been at fault. Long story short, I had enabled Speed Brain. I should have remembered that Speed Brain uses the 503 response code to indicate a failed cache pull. Unfortunately this means though that genuine 503 errors are getting absolutely swamped by a huge influx of Speed Brain related 503 errors in the analytics. With Speed Brain enabled it is completely impossible to get an accurate rate of 503 errors which have been caused by non Speed Brain related issues. I know the blog post justifies the use of 503 to prevent incompatibilities with services which have not had support enabled for speculative requests but this seems like a pretty major downside. On top of that, It does appear that 503's related to Speed Brains cache lookup failures are leaking and being interpreted by services which should not be interpreting them that way. Mainly Google Mrchant Center and Search Console (and possibly other tools) are somehow encountering these responses and disabling shopping listings/ads/search results
