Latency and audience
New York is the natural hub for the US East Coast: 5-10 ms to Boston or Washington DC, 30-40 ms to Miami (the natural gateway to LATAM), 70-80 ms to London, 80-100 ms to Madrid or Frankfurt. It is the right DC when your audience is US East, Canada or LATAM. Typical fits: US-first SaaS, fintech tied to NY markets, businesses with Hispanic-America traffic.
