A new paper published in Nature Communication by a group of IGCP 653-realted authors, led by Anders Lindskog is bringing global media attention once again to the Great Ordovician Biodiversity Event. Their article (here) indicates that the timing of maximum diversification does not overlap with the significant Middle Ordovician meteorite peak.
