so, the content still exists on the cdn nodes - you deploy to origin, and then it gets pushed out to the edge. so that’s actually not surprising. It won’t get deleted unless you delete the netlify site.
Is the .wtf site the correct site, now? This is what i see:
if yes:
I would suggest you delete the netlify site that feeds into marguerite.io through our dashboard, and create a new site, deploy the same code that is on wtf (if that, indeed, is the correct one) and then re-associate the .io domain name with the new netlify site containing the right content.
or, even, just change the site that current site that feeds into the .wtf site to have the .io domain name, if it is indeed the correct one.
