Did ACDC ever break up?

Could you please clarify whether the rock band AC/DC has ever officially disbanded or taken an extended hiatus from performing and recording together? Their longevity and resilience in the music industry have been impressive, but there have been rumors and periods of inactivity that have left fans wondering about the status of the band's future. So, have they officially called it quits, or are they simply taking a break before returning with new music and tours?
