Re: [Bitcoin-development] Network propagation speeds
Hey Christian, Could you sort the snapshots by date? At the moment they're kind of in a random order. Sometimes I wish we had real-time stats too but this is a great start.

Re: [Bitcoin-development] Network propagation speeds
Damn, that happens if I do the overview as an afterthought. Fixed :-) Real time (last 24 hours, last week, last month) are in the pipeline, just need to find the time to implement access to the collector from the webpage. -- Christian Decker On Wed, Nov 27, 2013 at 8:35 PM, Mike Hearn m...@plan99.net wrote: Hey Christian, Could you sort the snapshots by date?
