Reverse proxies are slow

2019-12-17 11:00, public reverse proxies (using haproxy) start experiencing performance issues. Requests take a long time to process.
14:00, we add two (sozu) reverse proxies to the pool.
14:15, sozu proxies are actually experiencing issues too. We removed them from the pool. We start cleaning them.
15:12, sozu proxies have been cleaned, updated and restarted. We add them to the proxy pool again.
16:25, things seem to run smoothly. We consider this issue fixed.
