The page-reading connectivity test is gone

The connectivity test on the old site tools settings has been removed along with that page. It let you enter a URL (or click the magnifier next to an allowed domain), run the same retrieval a real conversation would make, and see whether the page came back with real content or a bot-verification page. It isn't relocated and there's no lighter version of it.

What's left if you suspect a site blocks us: run the case in the playground and watch what the assistant actually answers with. The two settings the test used to replay (the domain policy and JavaScript rendering) are still there, with the values you had; both now sit on the web page reading configuration page.
