VERIO is recorded as a company in US. Current public evidence covers 2 domain references, 1 public website, 3 supporting public references; services, assets, and relationship context should be read with that evidence boundary.
An old VERIO customer is not really choosing between nostalgia and novelty. The live decision is more practical: whether the domain, mailbox, SSL certificate, DNS records, server files, support contacts and renewal settings are safer inside a consolidated web-presence platform, or whether the cost of moving them is now lower than the cost of staying.
