is one piece episode 579 filler?

The Thousand Sunny sails forward into the New World. The crew approaches an unknown burning island; however, none of the three needles of the new log pose points to the island.

Nami suspects that there is an anomaly but Luffy still insists on going to the island. The crew then receives an emergency call; Robin warns them that most of these calls are a trap setup by the Marines to track down pirates, which Luffy ignores and still answers the call.

It is revealed that the distress call is coming from a man in Punk Hazard.
