[Tech] Location churn: empirical data

[Matthew Toseland]

Below are links to my node's location logs. A lot of the location churn is 
within roughly a slice of 10% of the keyspace, and the central signal is 
reasonably clean... but this degree of variation is going to cause problems 
with routing and especially data retention IMHO (on a network of several 
thousand nodes, with *at least* 1000 nodes online at a time). There were a 
whole bunch of resets during the week 19 April to 26 April, and on the 24th, 
RC2 was released; on May 8th, 0.7.0 was released. These may explain some but 
not all of the long jumps...

Random resets:
It is possible there were random resets before the first mentioned below, 
because we didn't log them until some time after we started logging 
locations.

location)

I am asking Oskar about this...
