Summary

  • UK company 01750343, incorporated 6 September 1983, now trades as ALCATEL SUBMARINE NETWORKS UK LTD and lists STC SUBMARINE SYSTEMS LIMITED among its previous names — a documented chain of names with a number and a date.
  • The ARIN organisation handle SSS-10 still records STC Submarine Systems, Inc. with a complete contact section, while the five network fields BTW's compiled record enumerates — ASNs, prefixes, peering, facilities, IXPs — return nothing.

ARIN handle SSS-10 is a small record. It holds a name, STC Submarine Systems, Inc.; an alias, "Submarine Systems, Inc."; a registration jurisdiction of United States; and a legal type that BTW's compiled registry record still logs as unknown. Around that identity sit eight contact records and two people. Around it, too, sit five fields that would say what the organisation actually operates — ASNs, IP prefixes, peering relationships, facility presence and IXP presence — and in the compilation dated 15 October 2026, not one of them returns a result.

What the entry does carry is a responsible party. The record lists an abuse contact, and in its public form the mailbox is masked so that only the alcatel.com mail domain remains visible. That single string is the strongest live signal in the whole entry. It is also the weakest kind of evidence, because a mail domain tells you where someone reads messages, not whose authority they hold.

Now the second registry, and a different kind of evidence. A search of the UK register returns one company under this name: ALCATEL SUBMARINE NETWORKS UK LTD, company number 01750343, incorporated on 6 September 1983, with four previous names. The register's own words:

ALCATEL SUBMARINE NETWORKS UK LTD

Matching previous names: STC SUBMARINE SYSTEMS LIMITED · STC COMMUNICATIONS AND INFORMATION SYSTEMS LIMITED · ALCATEL-LUCENT SUBMARINE NETWORKS LIMITED · ALCATEL SUBMARINE NETWORKS LIMITED

01750343 - Incorporated on 6 September 1983

That is a chain of names with a number and a date attached, the kind of chain that survives because a registrar maintains it. It is not a chain of obligations. A previous-names list records what a company was called; it does not record which other legal persons, in which jurisdictions, were absorbed along the way.

The history is where the two records start to look like one story. A community encyclopaedia account states that "[i]n 1993, Alcatel Cable acquired the British company STC Submarine Systems (the successor company to the Submarine Telegraph Company) and its 34,000 m2 factory at Enderby's Wharf on the Greenwich Peninsula". Nokia's own company history places the same acquisition in 1994 and ties the business to what became Alcatel Submarine Networks. Both are cited here; neither is adopted as the date, and the discrepancy between them is a useful warning against treating any summary as the transaction record.

Later comes a group-level event that is not in dispute. Nokia announced on 14 January 2016 that it had completed its acquisition of Alcatel-Lucent, the transaction that brought the submarine-cable business inside the Nokia group.

None of that reaches SSS-10. The UK company is a "Limited". The registry entry is an "Inc." recorded against a United States registration jurisdiction. No document located for this article links the two: not a merger filing, not a name-change filing, not a transfer schedule. The nearest thing to a bridge is the mail domain on the contact record — alcatel.com, a string that also appears four times in the UK company's name history. Proximity is not succession.

A domain that matches a corporate name in another registry's previous-names list establishes that someone with an alcatel.com mailbox was once listed as this organisation's abuse contact. It does not establish that the company now answering at that domain has assumed the US corporation's obligations, or that it holds authority to act for the entry.

So the question splits in two, and the two answers are not the same size.

The first is answerability for the record. An entry with no visible resources, an unknown legal type and a contact on someone else's mail domain is still an assertion that an organisation exists and that a named party is responsible for it. The registry that keeps that assertion is the only party currently identifiable who can explain it: why it persists, when it was last attested, what its validation state is, and what happens to it if nobody claims it. That is an obligation about record quality, not a finding that the registry inherited a cable company's liabilities.

The second is answerability for the organisation. That belongs to a surviving entity that can be verified, to a legal successor, or to a controller expressly authorised to act — and on the material reviewed here, no party meets that test. The Alcatel-to-Nokia chain is the strongest lead and remains exactly that.

Four documents would move this from lead to finding. A US state incorporation, merger or dissolution record naming the corporation that used the name. A statement from Alcatel Submarine Networks, Nokia or any Alcatel-Lucent successor accepting or denying responsibility for the entry. An ARIN validation or change record dated after the last corporate event, naming the party that last attested it. And, if address space or an ASN ever left this handle, a transfer record showing where it went and on what date. Any one of these would replace an inference with a classification.

Why bother? Because the record is used. Someone escalating abuse traffic reads the contact field and acts on it. Someone assessing a transfer of legacy resources reads the organisation record and treats the name as a party. Someone tracing the history of a cable factory reads a registry entry and assumes a company behind it. In each case the reader inherits an assertion whose maker is not identified.

One boundary belongs here, once. The registry's own record text was not obtained: four attempts against ARIN's public endpoints, including the organisation record locator, returned no registration details, legal name, address or dates. The entry's creation date, its street address, its last modification and any past allocation therefore remain unestablished in this account. What is established is the shape of the identity as BTW's compiled directory record holds it, and the UK chain as the register states it.

Set the two side by side and the difference is not dramatic, it is structural. The UK name has a custodian: a numbered company, a date of incorporation, a current registered name. The US registry identity has a mail domain and an empty network. One of those is a fact about a company. The other is a fact about a database — and until a document closes the gap, it is a database speaking in a name that no one has agreed to answer for.
