Last month was pretty stable at about 5,000 simultaneous users all month.

This month is the first time we have actual usage numbers from Azure. They told us what the cost would have been, but did not actually charge us. This month (September) is the last month on the free grant we have for Azure. After that, we will probably have to throttle Azure just like the other backends. If you want to help make domain fronting more efficient and future-proof, a good place to direct your attention is to this ticket, which aims to start using domain fronting as a cheap, low-volume interface to BridgeDB, instead of as a bulk data transfer channel: https://bugs.torproject.org/16650

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

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

This is the first month where we have actual (not estimated) usage numbers, as a result of the new kind of account we're using. Unfortunately (also as a result of the account transition), meek-azure was broken until August 14, so these number really only represent half a month.

Zone 1 3726 GB $324.20 Zone 2 1206 GB $166.39 -- total 4932 GB $490.58
