Topic: Bitcoin p2p Network Status Charts. - page 2. (Read 10805 times)

I am not sure. The site uses this database:
http://software77.net/geo-ip/
to map the IP to a location. And that is what comes up for those IP addresses.

Should I consider that European Union means an aggregate of EU countries which are not already present on the list?
It's a bit confusing to see European Union with so many less nodes than many countries that are part of the Union...

PS: Great job by the way, thank you for such graphs.

Sorry half crashed again.

Thought it was stable now so turned off logging to save on costs! Have turned logging back on now.
Stats will be good again in 24hours.

It will be counted as a host, and listed in the country chart (as I will get an addr message from it).

But since I can not connect is will not be in the listening hosts or version charts.

About listening nodes:

If one node's connections are full (can it be ) always, is it undetectable?

Actually issue was that after the previous issue I made the database transactional, and never tested the delete process after this change. I now know that with Berk DB if the database is set to transactional you have to ensure you pass a transaction to the cursor when deleting!

I am starting to go off berkdb.

Sorry - just found another bug as you can see!

It had been running perfectly for 28 days since the last issue.

It purges IPs from the berkdb that have not connected for over 28 days. As you can see at about 21:10 last night the thread that updates the database tried to purge some old ip's for the 1st time and threw an exception that caused it to exit. I have now added another "catch" and is up and running again. As before will take 24 hours for the stats to be in line again.

Thought it was odd there were no version 5 clients.
It was odd! There was a typo in the command that generates the version charts. Now fixed. There are 28 running.

Thanks for the update.

Had a corruption in the BerkDB that tracks the connections. I have changed code to be transactional so should not happen again.

I had a backup, but this had the corruptions in too (the number was steadily increasing!).

Unfortunately the database had to be deleted.

It will take 24hours before the stats are correct again. I will clean up the charts in a few days time.

There was a bug - when I sorted the countries by number of connection I removed duplicates! This issue is now fixed.

total number of nodes is steadily declining. 

I noticed that some of the countries tend to disappear and reappear on the list.

For example, I saw Vietnam (~90 nodes) and Nigeria (~30 nodes) disappear and then reappear a few hours later. Since they each have more than a few nodes, I doubt that everyone in the country is turning of their clients.

Is there a particular reason for this?
 

It's not exactly what you're looking for, but the guy who runs this might be able to more easily add that information:

Starting to see a nice increase in version 0.4.0 usage.
Up to 405 at time of this post...



Note this chart only shows nodes that are allowing connections (i.e. not behind a firewall that is stopping incoming connections).

I'd be very interested in some statistics on how long it takes transactions and blocks to propagate across the bitcoin network. Could you collect some data on these times? I.E. Measure when you receive a particular tx or block from different nodes, and track something like the 95% percentile of the delay.

Having good data on this (especially for blocks) is relevant to any discussion of changing the blocktime to less than the current 10 minutes.

It is a shame that the CIA World Factbook does not just return numbers for population of each country.

It might be really interesting to see "number of hosts per capita" for each country.

Great site! Never take it down!

Just added the full list of hosts by country to the bottom of the front page. Makes interesting reading.
