[metrics-team] TorPerf graphs

[David Goulet]

Hello everyone!

This morning I noticed this change in the torperf graph on Metrics:

http://rougmnvswfsmd4dq.onion/torperf.html?start=2016-06-18&end=2016-12-18&source=all&filesize=50kb
http://rougmnvswfsmd4dq.onion/torperf.html?start=2016-06-18&end=2016-12-18&source=all&filesize=1mb

I put there at 6 months interval to see the _huge_ change in download time.
Same goes for the failure rate:

http://rougmnvswfsmd4dq.onion/torperf-failures.html?start=2016-06-18&end=2016-12-18&source=all&filesize=50kb
http://rougmnvswfsmd4dq.onion/torperf-failures.html?start=2016-06-18&end=2016-12-18&source=all&filesize=1mb

This seems to have started in mid-October and the only thing I can see there
is 0.2.8.9 being released with a security fix...

No surge of users or any change in bandwidth of the network as well:

http://rougmnvswfsmd4dq.onion/bandwidth.html

Did anything changed on Metrics side around that time? What Tor version is
being used for the client of Torperf? This is worrying me as a potential issue
that has been introduced recently destabilizing the network.

If nothing changed and this could be a legitimate issue, we should double
check with Rob's OnionPerf data.

Thanks!
David
