Data is supplied by Credit Market Analysis up to 9/30/10. After that data is from Thomson. To match on Datastream CMA CDSs (which end in Datastream on 9/30/10) to Thomson Reuters CDSs (which go past 9/30/10), see the DSS site. Also has credit default swap indexes too. However, these are not continuous (not "on the run") & only the CDS industry indexes are available after 9/30/10. Datastream is part of Refinitiv.
