The number of simultaneous users increased hugely in April, from 2000 to
around 5000. There are big increases around April 9 and April 15, which
I conjecture were caused by a performance improvement in meek-azure and
its coverage in TWN. meek-azure used to be hugely bottlenecked, but now
it should handle as many users as the others.

We moved over 10 TB in April.
Because of meek's extra layer of indirection, it doesn't correctly
compute per-country user statistics (the server sees the IP address of
the CDN, not of the actual user). Now that a nontrivial fraction of
bridge users use meek, a nontrivial fraction of bridge users are being
miscounted. Keep that in mind when you look at the per-country bridge
user graphs--if users are connecting through meek, they don't count
towards that country's total. Here is a ticket that aims to fix the
issue by passing the client IP through the CDN.

If you want to help reduce costs, you can
1. Use meek-azure; it's still covered through a grant for the next four
months.
2. Set up your own App Engine or CDN account. Then you can pay for your
own usage (it might even be free depending on how much you use).
Here are instructions on how to set up your own:
https://gitweb.torproject.org/pluggable-transports/meek.git/tree/appengine/README
https://trac.torproject.org/projects/tor/wiki/doc/meek#AmazonCloudFront
https://trac.torproject.org/projects/tor/wiki/doc/meek#MicrosoftAzure
Then you will have to enter a bridge line manually. Follow the
instructions at
https://trac.torproject.org/projects/tor/wiki/doc/meek#Howtochangethefrontdomain
but instead of changing the "front=" part, change the "url=" part.
For example,
bridge meek 0.0.2.0:1 url=https://<myappname>.appspot.com/ front=www.google.com
== App Engine a.k.a. meek-google ==
Both bandwidth and instance hours were up about 19%.
Here is how the Google costs broke down:
6304 GB $756.59
2597 instance hours $129.84
Compared to the previous month:
5316 GB $637.93
2173 instance hours $108.64
https://globe.torproject.org/#/bridge/88F745840F47CE0C6A4FE61D827950B06F9E4534
== Amazon a.k.a. meek-amazon ==
Both usage and cost were down a bit from the previous month.
Asia Pacific (Singapore) 114M requests $136.79 884 GB $117.92
Asia Pacific (Sydney) 443K requests $0.55 3 GB $0.34
Asia Pacific (Tokyo) 51M requests $61.03 305 GB $39.32
EU (Ireland) 173M requests $208.17 1598 GB $127.21
South America (Sao Paulo) 5M requests $9.91 23 GB $5.31
US East (Northern Virginia) 46M requests $45.56 418 GB $33.26
--
total 389M requests $462.01 3231 GB $323.36

== Azure a.k.a. meek-azure ==
meek-azure increased a lot because of improved performance this month.
