If you're just tuning in, meek is a pluggable transport introduced a few
months ago. https://trac.torproject.org/projects/tor/wiki/doc/meek.

            App Engine +  Amazon + Azure = total by month
February 2014    $0.09 +      -- +    -- =   $0.09
March 2014       $0.00 +      -- +    -- =   $0.00
April 2014       $0.73 +      -- +    -- =   $0.73
May 2014         $0.69 +      -- +    -- =   $0.69
June 2014        $0.65 +      -- +    -- =   $0.65
July 2014        $0.56 +   $0.00 +    -- =   $0.56
August 2014      $1.56 +   $3.10 +    -- =   $4.66
September 2014   $4.02 +   $4.59 + $0.00 =   $8.61
October 2014    $40.85 + $130.29 + $0.00 = $171.14
November 2014  $224.65 + $362.60 + $0.00 = $587.25
--
total by CDN   $273.80 + $500.58 + $0.00 = $774.38 grand total

Average usage (by count of simultaneous users) was about 3.04Ã greater
in November than in the October (750 users per day versus 247). See the
attached userstats-bridge-transport-meek-2014-09-01-2014-11-30.png.

The number of users was 3.04Ã according to Tor Metrics, but the cost for
meek-google was 5.50Ã and meek-amazon was 2.78Ã. A possible explanation
is that in addition to gaining more users, each user is also using more
bandwidth. App Engine bandwidth was up 4.76Ã compared to last month and
Amazon bandwidth was up only 2.65Ã.


== App Engine a.k.a. meek-google ==

Google is migrating App Engine accounts to their new "Cloud Platform."
Because I had to create a new Cloud Platform account, I got a free trial
credit of $300. For technical reasons (relating to the Cloud Platform
migration) I couldn't apply the credit until November 11. Up to then, we
had been charged $75.70 for the month. The remaining $148.95 was paid
by the credit. After this one, I have another $500 credit, which should
get us into the new year.

Here is how the costs broke down:
	1375 GB             $165.10
	1191 instance hours  $59.55
The attached meek-google-costs-2014-12-01.png shows the breakdown of
costs between bandwidth and instance hours for the last few months.

The attached meek-google-2014-12-01.png shows B/s for the month. There's
a nice visible daily and weekly cycle.


== Amazon a.k.a. meek-amazon ==

The Amazon bill breaks down in a complicated way by region.

Asia Pacific (Singapore)	 76M requests	 $91.43	 500 GB	 $75.34
Asia Pacific (Sydney)		245K requests	  $0.01	   1 GB	  $0.25
Asia Pacific (Tokyo)		 27M requests	 $33.05	 160 GB	 $26.23
EU (Ireland)			 50M requests	 $58.34	 490 GB	 $51.78
South America (Sao Paulo)	450K requests	  $0.00	   3 GB	  $0.06
US East (Northern Virginia)	 13M requests	 $13.12	 115 GB	 $12.99
--
total				167M requests	$195.95	1269 GB	$166.65


== Azure a.k.a. meek-azure ==

Azure is still on a free grant for a year. Unfortunately I don't see a
way to find out what it would be costing or even get a report of monthly
bandwidth usage.

The attached meek-azure-2014-12-01.png shows GB/hour for the last seven
days of the month.
