Hello,

we have now finished writing a tech report with the results of these
statistics. You can find it in PDF form here:
https://research.torproject.org/techreports/extrapolating-hidserv-stats-2015-01-31.pdf

We are currently working on a more casual-reader-friendly blog post,
which will contain additional information that the Tor community might
be interested in. You will find it in blog.torproject.org in two weeks
from now or so.
