Not sure what to make out of this though:

"The chart for download latency among Germany's leading ISPs reveals significant variability and
performance differences. Hetzner stands out with a notably high median latency of 190 ms, considerably
higher than its peers, reflecting its unique position with potentially larger variations in network
performance, as indicated by its high standard deviation (87 ms) and wide interquartile range (IQR)
stretching from 144 ms to 258 ms. In contrast, Deutsche Telekom and Telefonica show similar median
latencies around 75 ms, with Deutsche Telekom displaying a slightly wider IQR (48 ms) compared to
Telefonica (44 ms), suggesting a broader distribution of latency values among its users. Versatel (1&1)
presents the lowest median latency at 37 ms, paired with a relatively compact IQR (35 ms), indicating
more consistent and potentially efficient network performance. Vodanet, despite a median latency (42
ms) comparable to Deutsche Telekom and Telefonica, exhibits higher standard deviation (51 ms)."

My point is hetzner is a hoster, not an ISP, let alone a leading ISP... now I consider numbers from hosters quite interesting, but I do have reservations if a study paints with too broad a brush.

I will be careful to interpret any other data in there (in spite of liking the carefully statistical representations and tests, but if the inputs are garbage... GIGO still applies).
