While Loy was earning a law degree at the University of Notre Dame, his blog, then entitled The Irish Trojan's Blog, gained moderate attention on the internet and in some media outlets. Loy's hyperactive blogging on Hurricane Katrina, particularly urging evacuations at a time when local authorities had not yet acted and much of the national media was still largely focused on threats to Florida rather than Louisiana, resulted in coverage by several media sources.
At 1:57 p.m. on Friday, August 26, 2005, nearly two days before Mayor Ray Nagin of New Orleans issued a mandatory evacuation of the city, Loy wrote, "At the risk of being alarmist, we could be 3-4 days away from an unprecedented cataclysm that could kill as many as 100,000 people in New Orleans...If I were in New Orleans, I would seriously consider getting the hell out of dodge right now, just in case." Later that day, Glenn Reynolds of InstaPundit linked to Loy's site, causing thousands of people—including some in the New Orleans area—to view his warnings. Loy's site became increasingly heavily trafficked as Katrina approached and eventually made landfall, and ultimately became the "most frequently cited hurricane-related blog" for Katrina-related coverage, according to Intelliseek's Blogpulse.
