In addition to not being able to upgrade to Open Data 2.0, our 1.1 version site became not accessible through our costumed domain http://data.cuuats.org, but still functions under the full URL “http://cuuatsdata-ccgisc.opendata.arcgis.com”. Outr CNAME is correctly pointing to opendata.arcgis.com. Could any staff check whether it was because the upgrading process was not successful, and recover the costumed domain link since it was the url we advertised to all our users? Please don't hesitate to contact us via swuzhati@ccrpc.org or 217-819-4072.
Hi! Your custom domain has been recovered. I also emailed you and thank you for posting your issue on geonet.
Thank you!
