 Replying to [comment:3 asn]:

 A big consideration here is latency; i.e., proximity to App Engine
 servers. We're adding an extra roundtrip hop to every communication:
   meek-client → App Engine → meek-server
 We have no control over the meek-client→App Engine link, but we can try to
 make the App Engine→meek-server link fast.

 Here are sample roundtrip times for a few servers. The test is running
 live at http://meek-latency-test.appspot.com/. Source code for the test is
 in the repo [https://gitweb.torproject.org/pluggable-
 transports/meek.git/tree/a201ed6e7d14de1b1187311e77bf6d147e4b3205:/latencytest
 here]. The horizontal axis is milliseconds.

 The measured servers are in order:
  1. my bridge in California (the same one used for flash proxy)
  2. my bridge with HTTPS turned on
  3. a bridge in Greece
  4. a Google server very close to App Engine (lower bound on roundtrip
 time)
  5. an HTTPS Google server very close to App Engine (lower bound on HTTPS
 roundtrip time)
 I can add other servers if someone wants to test their own.

 It appears that the App Engine requests are coming from 8.35.201.0/24 in
 the U.S.
 [https://developers.google.com/appengine/docs/go/gettingstarted/uploading
 This link] seems to confirm that the servers are in the U.S. Ideally we
 minimize latency with that netblock.

 All that said, I've been using the Greek bridge for a while, and it
 doesn't feel that slow, but maybe I'm just used to it.
