Hi Mike,

I am glad you are still following up= with Bitnodes. The recent spike in nodes count should probably be taken wi= th a grain of salt; run #231 (h= ttp://getaddr.bitnodes.io/231/) does appear artificial to me, i.e. pote= ntially bogus nodes being added. I am still working on a more in depth anal= ysis on the data.

There are quite some TODOs for the project at the momen= t for the next couple of months. I have included propagation data as well i= nto the list.

Cheers,
Addy

Thanks. By the way, your bitnodes site is excellent. Thank= s for doing that. If you're in the mood for extending it, it'd be g= reat to gather and chart data on block and tx propagation times.

Do you think the recent explosion in running nodes is real, or due to = some kind of custom experimental thing?

Despite that I have= 87 connections from regular nodes, virtually all transactions seen by my n= ode are being announced by this modified software, which appears to run on = several different machines.

I am wondering if anyone out there knows/owns these nod= es and if they are relaying transactions without checking their validity. T= hat seems the most likely reason for how they are always able to win the ra= ce to be the first to announce to my node.
