The people responsible for keeping data readable across decades are mostly institutions, they mostly use .org, and they think about scale in exactly these units. Digital preservation is the reading that makes this pairing work.
The exabyte moved from theoretical to operational in about a decade. Global data volumes are measured in them, hyperscale storage is sold in them, and the prefix is now working vocabulary.
Ebyte compresses that into five characters, reading as a data or storage company, an infrastructure business, or a technology publication. The e- prefix also carries the older electronic connotation that has been in branding since the nineties without ever quite leaving.
On the .org it equally suits an open data project, a standards body, or a research organisation.
Five letters, two syllables, no spelling problem, and a root that gets more current as data volumes grow.
The name is available. Enquiries welcome.
