My initial thought for this: create a simple redis db for storing key
value pairs of instance -> list of live instances for each privacy front
end (libreddit, bibliogram, etc). A script executed on a certain
schedule would (in the background) check each instance to make sure it
isn't down or unreasonably slow. If the instance is available, add it to
a list of available instances in the db.
When a user navigates to the revolver url (something like
<url>/<service>/<...>), the app would pick a random value from the list
returned by redis.get('<service>') and forward the user to that
instance.
As a side note, this could instead load the instances json from a remote
source (like github or something) so that changes to instances don't
need to involve a redeploy of the entire app.
