The number of simultaneous users was up again in March, reaching 2000 simultaneous users some days. The fluctuation between weekdays and weekends was greater than we've seen before.

We moved something over 9 TB in March. We're getting close to where CDNs start offering price breaks :/

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

At the end of February, I tried tweaking some performance parameters to try and reduce instance hours. It seems like it worked, as instance hours were down 31% as bandwidth was up 29%.

Here is how the Google costs broke down: 5316 GB $637.93 2173 instance hours $108.64 Compared to the previous month: 4114 GB $492.71 3226 instance hours $157.82

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

meek-amazon was up quite a bit compared to the previous month. Requests were up 6% and bandwidth was up a whopping 42%. The big increases were in the Asia Pacific (Singapore) region and EU (Ireland) region.

I think we're going to go ahead with removing meek-amazon from Tor Browser. This will take a little bit of work--I'd like there to be a blog post that explains how to set up your own Amazon instance if meek-amazon is currently working for you. I also would like to try and work out any performance issues with meek-azure in order to use it as a replacement.

Weirdly, there were over 24,000 plain HTTP requests from the US East region. That is strange because meek is HTTPS-only. The number of HTTP requests is still small compared to the 44,000,000 HTTPS requests received from the same region, but it's far above other regions, which have at most a few dozen HTTP requests.

Asia Pacific (Singapore) 171M requests $205.57 1433 GB $195.60 Asia Pacific (Sydney) 156K requests $0.20 1 GB $0.17 Asia Pacific (Tokyo) 10M requests $12.05 70 GB $9.07 EU (Ireland) 158M requests $190.03 1486 GB $118.34 South America (Sao Paulo) 3M requests $6.70 17 GB $4.03 US East (Northern Virginia) 44M requests $44.00 378 GB $29.92 -- total 386M requests $458.55 3385 GB $357.13
