Well, let's see what rips were uploaded that day:
 * Hetler's Theme - Super Famicom Wars, a melodyswap with "Meet the Flintstones"
 * Showdown - Kirby Mass Attack, a melodyswap with "Smooth", and Undertale
 * Seasonical Astronomy Fantasy - Touhou 16: Hidden Star in Four Seasons, an arrangement
 * Prinsengracht - The Secret Annex Online, a Holocaust joke (and the rip you're referring to)
 * Tanetane Island - MOTHER 3, a STYLISH rip featuring sentence mixing
 * Polluted Pump (Pump Man Stage) (Beta Mix) - Mega Man 10, an arrangement of "Pumped Up Kicks"
 * Route 111 (German Release) - Pokémon Ruby & Sapphire, another WWII joke
 * Heat Wave - Bionic Commando, a melodyswap with "Patched Plains"
 * Space Invadres - Space Invadres, a rip featuring Darth Vader (saying "Nooo!") and "VADER TIME"
 * Shadilay - Pokémon Clover, a rip of "Shadilay" (an in-joke for 4-chan users)

Based on this list, no, it isn't an event. 2 rips were uploaded referencing Hitler's birthday out of 10 rips uploaded on that day. The rest were unrelated.
