Maybe something like this: https://gist.github.com/sdstrowes/cb67ca755c50bbb2f23ce384750f2048 - take all yesterday's traceroutes - pick out only hops <= 2 that weren't errors or timeouts - calculate quantiles for those per probe/af/hop, and also count how many traceroutes ran - retain only those probe/af/hop rows with a median RTT >= 495 and `n` traceroutes > 100 Cheers, S.
