We had about 2 dozen fasadas configured, deployed, and ready to serve production traffic at any given time.
But we only kept 4-6 actually active for `occrp.org` (and some others for other sites we hosted).
The other ones were an "emergency stash".
If an active fasada did go under, we'd swap its IP address out of occrp.org A records, and add one of the currently healthy standbys instead.
If we started getting way more traffic than the current active fasada set could handle, we'd add more.
