Kusto Tor Exit Nodes Historic Table

Description


This data represents a historic dataset of Tor exit nodes.

Source


Taken from the publically available resource on the Tor Projects own site https://check.torproject.org/torbulkexitlist

Why should I use this data?


It’s a high fidelity data set given it comes from the Tor Project themselves to identofy Tor usage. It is useful to find Tor nodes within existing datasets and represents a snapshot of the Tor environment on a specified date. This data set started collecting data 1 May 2024.

Disclaimer

Please note dependant on how this dataset evolves (eg data set creation processing size and Kusto ingestion processing) it may be changed to only include a specific time window (eg last 365 days of data).

Updates


Daily at around 0300UTC although source data is updated more regularly.
