Sometimes DuckDNS goes down partially, their servers breaking for about a week is why I purchased a domain and now host via Cloudflare.
Edit: One of my DuckDNS domains works internally, so at least it’s not a systemwide issue. Perhaps one of their relays…
I got one recently by B&H Photo Video, may have got lucky but the drive was brand new and untampered, and was in plastic cushioning, in a fitted box, inside 6" of airbags, inside another box. Delivered by DHL Express.
