Do you have link to the failure @stephentoub ? I assume this is OSX?

Seems related to #29428. The assert is confusing but it is on path where ping timed out.

this should be fixed by dotnet/corefx#37284 submitted on Apr 30.
All the info is now gone so it hard to know if that was part if the failing PR. I did check Kusto database and there is no other failure so I'm gonna close it for now.
Note that there are other failures with timeout, probably related to overall CI and name lookup stability.
