The Swift Gamma-Ray Burst satellite made the detection, with follow-up and additional observations from ground-based observatories and instruments, including the Gamma-Ray Burst Optical/Near-Infrared Detector (GROND) and the Very Large Telescope. At 12.8 billion light-years and redshift of 6.7, the burst was the most distant GRB observed until GRB 090423 on April 23, 2009.
