Indeed.

I didn't. Thanks.

Interesting. I'll see if I can find out when a majority of directory
authorities upgraded to 0.2.6.x.

the Tor network recently lost a large amount of relays (~75 or more)
due to BadExit attacks. this may account for a large sum of the
disappearing nodes (~20%), but it doesn't account for nearly all of
them.

I doubt that 25 Mpbs is 23% of the tor network capacity, I guess it
should say GBit/s.

Unfortunately I've got no historic onionoo details data that goes back
to 2014 to compare with current data, but if anyone has, feel free to
upload it somewhere.

You probably also know about the 0.2.3.x relays:

My uninformed guess would be that the higher minimum bandwidth requirements in 
v0.2.6.x forced out the marginal relays.

[tor-relays] Drop in relay count

2015-05-03 Thread Linus Nordberg 
Hi,

Looking at the graphs showing the number of relays in the network it
seems like we've lost about 500 (-7%) relays since the beginning of this
year.

  
https://metrics.torproject.org/networksize.html?graph=networksize&start=2015-01-01&end=2015-05-03
  
https://metrics.torproject.org/networksize.html?graph=networksize&start=2012-01-01&end=2015-05-03

Looking at the graphs showing the total relay bandwidth of the network
it seems like the advertised bandwidth has increased with about 25 Mbps
(+23%).

  
https://metrics.torproject.org/bandwidth.html?graph=bandwidth&start=2015-01-01&end=2015-05-03
  
https://metrics.torproject.org/bandwidth.html?graph=bandwidth&start=2012-01-01&end=2015-05-03

Seems a bit contradictory at first sight. A guess would be that a lower
number of fast relays have replaced a higher number of slow ones but I
haven't looked into it more.

Anyone who's looked into this? And can back up their theory with some
numbers.

Thanks,
Linus
