I have removed multiple layers from Open Data and layers are still showing in Open Data Portal with a 404 error.
Waited 24 hours
Open Data Hub and refreshed the items
Manually refreshed items in question
Some Stale items will not remove from Open Data
Click on 2013 International Roughness Index or 2013 Pavement Index. These along with the 2014 & 15 pavement friction and indexes have been removed from the groups that feed open Data.
Thoughts? I may open a ticket after another 24 hours.
