The rate limiting of meek-google and meek-amazon has been partially effective in bringing costs down. The bill this month is the lowest it has been since February. I aimed to get the meek-google bill down to $500, the amount of the monthly grant we're getting from Google, and it came in a little above that. meek-amazon, on the other hand, did not decrease much at all. I think it may be because of Amazon's per-request billing.

The number of users was pretty stable, staying mostly in the range 3000–4500.

If you want to set up your own bridge and CDN instance without rate limiting, I can help you do it. Here are some docs to look at: https://trac.torproject.org/projects/tor/wiki/doc/meek#Howtorunameek-serverb... https://trac.torproject.org/projects/tor/wiki/doc/meek#GoogleAppEngine https://trac.torproject.org/projects/tor/wiki/doc/meek#AmazonCloudFront https://trac.torproject.org/projects/tor/wiki/doc/meek#MicrosoftAzure

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

Rate limiting brought down bandwidth usage almost 50%. Despite that, instance hours went up. The rate limiting happens at the bridge, so it's possible that requests are taking longer to process at the App Engine level, requiring more instance hours.

Here is how the Google costs broke down: 2807 GB $336.87 5299 instance hours $264.96 Compared to the previous month: 5359 GB $643.07 4571 instance hours $228.57

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

Bandwidth use was down about 16% compared to the previous month. The number of requests stayed about the same.

As you can see, the major contributor to the Amazon bill is not bandwidth but the number of requests. I hope this ticket will help reduce the number of requests we make: "Use streaming downloads" https://trac.torproject.org/projects/tor/ticket/12857

Asia Pacific (Singapore) 114M requests $136.84 831 GB $111.35 Asia Pacific (Sydney) 845K requests $1.06 2 GB $0.40 Asia Pacific (Tokyo) 57M requests $68.43 336 GB $43.11 EU (Ireland) 184M requests $221.41 1454 GB $108.52 South America (Sao Paulo) 8M requests $18.87 53 GB $12.54 US East (Northern Virginia) 64M requests $64.23 422 GB $33.25 -- total 429M requests $510.84 3101 GB $309.17

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

meek-azure bandwidth use continues to increase, up 17% compared to the previous month. Keep in mind that our grant expires in October, so you should not count it continuing to work after that.

Speaking of the grant, they switched me over to a new kind of sponsored account that will enable me to see the exact bandwidth use and what its cost would be. That should be available starting next month. Until now, we have had to estimate bandwidth usage by measuring at the bridge.
