Do you have ideas? I think this might be due to missing route: objects for your announcements. I see that you created them for the separate /23s a few hours ago, so you should wait for the upstreams to pick them, which might happen in the next 24 hours, so they can adjust their filters. You could also hope that some engineers pick it up here on list - as you asked - and adjusts filters before the scheduled time comes.

R: Re: Autunomous system filtering?
Thank you Massimiliano. Consider that when we were announcing the whole /22 everything was working correctly, then suddenly some ASs stopped to accept our prefixes. That's why we decided to split the network and announce prefixes with different AS. Moreover the /23 announced by AS2876 spreaded correctly, even if the object has been created at the same time as the other...

So when AS28716's upstreams rebuilt the inbound filter, 185.85.20.0/22 got dropped. When AS28716's upstreams update the filter again, 185.85.22.0/23 should become visible. It looks like the route object for 185.85.20.0/22 has been deleted. Is there a whowas service for routing registries? Yang
