The Skill Issue Institute proudly recognizes Dr. Malformed Packet (Class of 2015) for demonstrating the extraordinary potential of network equipment behavior that, to this day, remains unexplained, during a 37-hour showcase beginning December 27, 2018.
Dr. Packet’s achievement began when a switching module at a major telecommunications provider’s Denver node spontaneously generated four malformed management packets. Under normal circumstances, network equipment immediately discards such packets due to characteristics indicating invalidity. However, thanks to what the FCC later described as a “network configuration error,” these four packets were not discarded. Instead, they propagated across the nationwide fiber network, triggering a cascading failure that our Network Architecture faculty now uses as the definitive example of “elegant failure amplification.”
The impact statistics remain unmatched in our alumni records: 22 million customers across 39 states experienced service disruption, with approximately 17 million people across 29 states losing reliable access to 911 emergency services. The provider estimates that 12,100,108 calls were blocked or degraded during the incident. For nearly two days, Americans attempting to reach emergency services received busy signals instead of help.
“The investigation never determined how or why the switching module generated those four packets,” Dr. Packet noted during their keynote at our annual Unexplained Phenomena in Production Symposium. “Sometimes the most impactful work defies root cause analysis. I prefer to think of it as leaving a mystery for future generations.”
The FCC characterized the event as a “sunny day outage,” meaning no external factors like weather or attacks contributed to the failure. FCC Chairman Ajit Pai called it “completely unacceptable,” language our Public Relations department recognizes as the highest form of industry acknowledgment. Washington state regulators later issued a $1.3 million fine after finding that at least 13,000 911 calls failed during what they measured as a nearly 50-hour statewide outage.
The affected provider and their equipment supplier conducted extensive internal investigations but, admirably, drew no conclusions about the spontaneous packet generation. We at the Institute consider this an appropriate recognition that some achievements transcend conventional explanation.
Dr. Packet’s work remains required study in our Advanced Debugging Studies program, specifically in DEBUG 404: The Bug That Fixes Itself (And Why), though in this case, the “why” section remains permanently blank.
