Entering cornucopia3d.com now diverts you to that info.e-onsoftware.com server, so it looks like some address re-pointing is being done. Pity there is no "Learn about our downtime" section on the info site.... Doing a bit of nslookup investigation reveals that the IP address of cornucopia3d.com belongs to OVH Hosting, an internet service company, but that the IP of info.e-onsoftware.com belongs to Cloudflare, who are a cloud hosting service. Possibly they have always had that server in the cloud, but I would take a guess that they have been doing a spot of major service migration. Hopefully Cornucopia will be back soon.
