 The data sets are available at the [SURF/CWI data repository](https://repository.surfsara.nl/datasets/cwi/ldbc-snb-interactive-v1-datagen-v100). We also provide [direct links](https://ldbcouncil.org/data-sets-surf-repository/snb-interactive-v1-datagen-v100) and a [download script](https://ldbcouncil.org/data-sets-surf-repository/#usage) (which stages the data sets from tape storage if they are not immediately available).
