When I scan the extra-info data from July for routers that reported more
bandwidth read than written in a given 15 minute interval I find quite a
few examples. Here's one:

written against
5955584,11724800,10200064,25600,1619968
read. That's probably not just directory fetches. My guess it's client
bandwidth. There may even be cases where it's hidden service bandwidth -
if the service is running 'locally'.
I ran a scan against the 30th July to pull the routers this happens to. I
only pulled the guys that reported a 4MB plus difference for any given 15m
interval. The same guys show up again and again, so they are doing
something different to everyone else.
