UUNET Technologies

UUNET Technologies was one of the first commercial Internet service providers, founded in 1987 by Rick Adams in Virginia to commercialize Usenet and email, launching the AlterNet IP backbone in 1990. Backed by Accel Partners, Menlo Ventures, and NEA, it IPO'd on NASDAQ in 1995, was acquired by MFS Communications for $2B in 1996, which WorldCom bought that same year; after the MCI merger and Verizon's 2006 acquisition the UUNET brand was retired into Verizon Business. The brand is defunct today - its legacy domains (uu.net, uunet.com) remain Verizon-operated DNS zones whose web hosts only redirect to verizon.com/business, and it publishes no APIs or developer surface.

UUNET Technologies is profiled on the APIs.io network. Tagged areas include Company, Internet Service Provider, Networking, Telecommunications, and Internet Backbone.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/uunet-technologies: open an issue to ask a question, or submit a pull request to add artifacts.
