design docs in https://help.torproject.org/tsa/howto/cache/
launch checklist:
1. alternatives listing and comparison (done)
2. deploy a test virtual machine by hand, say `cache-01.tpo` (done)
3. benchmark the different alternatives (done, ATS and nginx comparable)
4. setup secondary node with Puppet, say `cache-02.tpo` (in progress,
missing puppet config)
4. validation benchmark against both nodes
5. lower DNS to 300 seconds, wait an hour
6. flip DNS to the cache node, wait and monitor for 5 minutes
7. raise DNS back to 1h if all goes well.
Disaster recovery:
1. flip DNS back to pantheon

Comment (by anarcat):
ATS `Host` header bug was solved (set `pristine_host_hdr` to `1`) and
benchmarks performed, results in the wiki.
now setup nginx and setup benchmarks as well, on a secondary VPS hosted in
hetzner cloud.
benchmarks seem to show Nginx performance is comparable or faster than
ATS.
