We report on the status of on-going, deep multi-band observations in the field around the z=6.31 QSO SDSS J1030+0524, where an overdensity of candidate Lyman Break Galaxies at the QSO redshift was found. The observations include a large program with Chandra, deep JVLA observations, and a strategic LBT program for optical spectroscopy. Additional imaging and spectroscopic coverage is provided, among others, by HST, VLT/MUSE, Keck and Spitzer data. The J1030 field is currently the 4th deepest X-ray survey, one of the few radio fields observed at microJy depth, and the only deep multi-band survey in a highly biased region of the early Universe. We are collecting and organizing all multi-band data in a public database that can be effectively exploited by the AGN community. Examples of preliminary results from these data include: i) the first spectroscopic confirmation of a few galaxies at the redshift of SDSS J1030+0524, and ii) the discovery of a proto-cluster at z=1.7 around a Compton-thick FRII radio-galaxy.
