I occasionally get timeouts or 503 errors from ArcGIS Online (AGOL) Feature service, if I instead would implement this using HttpCaller (and using the rest api) I have much more possibility to tune for increased resilience using featres such as editing timeouts, specify number of retries and even parallel processing.

It would be great if we could specify these in the FeatureReader/Reader as well!

​@nordpil ​@raghavendrans This is a known issue with ArcGIS Online. See this thread. You need to take these 2 bugs (BUG-000123780 and BUG-000124290) and notify esri that they still are occurring because it looks like they marked them as not reproducible ​@bruceharold  🤦 The solution the AGOL product team gave me (I worked on this case quite a long while) is to retry and backoff the requests, which is implemented in FME starting at 2019.1, so what you’re seeing is extended issues.

This issue is happening because the ArcGIS Online CDN (AWS Cloudfront) can’t handle the number of requests it’s receiving (which is shared infrastructure with every other AGOL org) and/or you’re org is doing a lot of requests to AGOL.

During my esri case (I spent at least 2 or 3 months on with Premium Support), I got to a point where I had an FME job setup to send an email to support (within my case) every time these errors popped up, so maybe you can do the same once you open a support ticket?

​@PierreAtSafe you can close this as Safe has already done all it can.
