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 3.04× 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.

https://metrics.torproject.org/userstats-bridge-transport.html?graph=userstats-bridge-transport&start=2014-09-01&end=2014-11-30&transport=meek

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


== 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.
