 * ROBLOX eventually shutting down the forums
 * Quackity's subscriber count unnoticeably plummeting

However...


 * Does not cause maintenance
 * Does not affect users
 * Does not affect sales and catalog
 * Does not trigger a blog

The April Fools 2012 hack can be similar because it meets all of the criteria:


 * Caused maintenance
 * Affects users
 * Affect sales and catalog
 * But does not trigger a blog

That event was unforgettable to the ones that were alive in that time.
