CyberBunker
Internet Service Provider
CyberBunker was an Internet service provider located in the Netherlands and Germany that, according to its website, "hosted services to any website except child pornography and anything related to terrorism". The company first operated in a former NATO bunker in Zeeland, from which it got its name, and later in another former NATO bunker in Traben-Trarbach, Germany. Sven Olaf Kamphuis referred to CyberBunker as the Republic of CyberBunker and referred to himself as the Minister of Telecommunications and Foreign Affairs.
CyberBunker served as a web host for The Pirate Bay and as one of the many WikiLeaks mirrors. CyberBunker has also been accused of being a host for spammers, botnet command-and-control servers, malware, and online scams. The company has also been involved in Border Gateway Protocol hijacks of IP addresses used by Spamhaus and the United States Department of Defense. The Spamhaus hijack was part of an exceptionally large distributed denial of service attack launched against them in March 2013. Because of the size of this attack it received considerable mainstream media attention.
As of 2013, CyberBunker listed its address as the bunker, but the location of CyberBunker's servers was unclear.
In September 2019, the German police stormed and shut down the company's operations in its bunker in Traben-Trarbach.

Why this record matters
The phrase “internet Service Provider” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q4036791. Authority coordinates are 51.502, 3.907. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2013 and 2019.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
