I haven't been able to get a successful query through since opening the ticket, but it appears to be intermittent. Looks like the first error was ~1.5hrs ago but the error count doesn't _look_ high enough that it's failing on every request.
New error: ThinkingSphinx::ConnectionError: Error connecting to Sphinx via the MySQL protocol. Error connecting to Sphinx via the MySQL protocol. Can't connect to MySQL server on 'ec2-54-242-154-181.compute-1.amazonaws.com' (111) - SELECT * FROM `matter_core`, `matter_delta` WHERE `sphinx_deleted` = 0 ORDER BY `updated_at` DESC LIMIT 0, 20; SHOW META

Just further to this: the Sphinx proxy is now working again on
what was the primary server (which is now the new failover).
Considering this issue resolved, but if you see a return of it, do
let me know!
