And how is this measured? Maybe it says more about the systems that are doing the measuring, than it does any the systems being measured?

According to bitnodes: Network speed of a reachable Bitcoin node is measured once per day by downloading a sample block from the node. The aggregated data includes only reachable IPv4/IPv6 nodes that do return block data at the time of measurement.
Interesting. Thanks for that. I guess I should have checked myself 🙂
Do they consider only archival nodes, and request a random block uniformly going back to the genesis block? Or just from the most recent few hundred blocks?
I ask because this might be basically about increased size of the chain. More blocks means the node is IO-bound while searching for an old block
Also, are recent blocks bigger? My BlockStats Explorer suggests that blocks are getting bigger in the last year or two
