The most recent mystery failure in Western infrastructure occurred during the Christmas period. Regardless of the usual suspects' involvement, it is imperative for democracies to expeditiously grasp the lessons to be learned.

In Europe, Christmas Day provided a temporary reprieve from the usual hustle and bustle, creating an atmosphere of peace and joy. Unfortunately, this tranquility was short-lived as a mysterious malfunction in the widely employed GPS satellite positioning system occurred on the subsequent day, affecting the Baltic Sea region.

The true culprits behind the incidents may forever remain unknown, although the most likely explanation points towards Russian involvement. In the autumn of 2023, when three data and energy connections on the Baltic seabed were attacked, both Russian and Chinese vessels happened to be directly above the targeted sites. It was subsequently revealed that a Chinese ship had accidentally severed a gas pipeline by dragging an anchor across it. Finnish sources placed blame on Russia for another attack.

Despite the circumstances, the Boxing Day traffic jam serves as a clear example that aggression can manifest itself unexpectedly, at any given moment, and through the utilization of any tool.

The occurrence of significant GPS phone jamming in Southern Sweden, Northeastern Germany, and extensive regions of Poland on December 26 was immediately apparent to pilots, aviation enthusiasts, and individuals relying on platforms such as GPSjam.com.

In the course of a regular day, the GPS jam map of Europe west of Russia predominantly exhibits shades of green, indicating minimal GPS interference ranging from 0% to 2%. Occasionally, a few yellow dots emerge, signifying a slightly higher interference level of 2% to 10%.However, the situation took a turn on December 26th when a considerable stretch of land and water, encompassing Växjö in the north, Stralsund and Neubrandenburg in the west, Łódź in the south, and Białystok in the east, turned red. This change in color indicated a GPS interference level surpassing 10%. While GPS wifi jamming had affected northern Europe in the past (particularly northern Norway and Finland), this occurrence stood out as the most severe one to date.

The occurrence of GPS jamming creates a notable hindrance for individuals relying on Google Maps, Apple Maps, and other location services, as the reliability of directions becomes questionable, making navigation more challenging.

The annoyance caused by GPS signal jamming extends beyond ordinary citizens and becomes a major inconvenience for pilots who heavily depend on GPS for navigation and landing. Nevertheless, pilots are well-prepared to manually land their planes in the presence of GPS interference, alleviating any concerns about them mistakenly landing on a non-existent runway.
