Over the past few months, many of you have reached out, wondering what became of the content once available on Station HYPO. Since launching in 2015, Station HYPO has shared nearly 2,500 posts—most focused on cryptologic history—and has become a valued resource for researchers, historians, and institutions such as the U.S. Naval Academy and several museums.

Rest assured, the content hasn’t disappeared—it’s simply no longer hosted here. Naturally, that raises the question: why the change?

Let’s just say, sometimes shining a light on certain issues comes with unintended consequences.

Earlier this year, I authored an article titled “Cryptologic Warfare Afloat Needs a Reset,” which was published in Proceedings, the professional journal of the U.S. Naval Institute. The article offered a candid critique of modern-day afloat cryptology. Prior to publication, it was cleared by both the Operations Security Officer and the Public Affairs Officer—steps I believed fulfilled my responsibilities.

However, I later learned that an additional pre-publication review was required—something I was unaware of at the time. That oversight led to an investigation and a formal letter of caution, citing a breach of policy and my NDA.

Given the visibility and scope that Station HYPO archived, I made the decision to remove the content—for now. The goal is simple: to reduce exposure and allow time for reflection. Many of the original posts will return when the time is right.

Thank you for your continued support and understanding.
