Considering #64 a duplicate of this: these 50x spikes on 0.5 are due to the timeout issue described there
from services-engineering.
mozilla-services/syncstorage-rs#794 seems to have solved this
from services-engineering.
To elaborate, we were seeing nodes get into these "stuck states" of either not responding entirely, or taking very long to respond. As described in #64 (and #61 (comment)), we even saw time outs on endpoints that did not checkout a db connection.
bb8 has potential connection leaks, and worse is its Drop impl. was potentially blocking our event loop, explaining time outs even when no db was involved.
Switching to deadpool from bb8 has fixed the timeouts or "stuck state".
This was a significantly different issue from the "stuck state" we're seeing on prod under 0.4.x.

Reopening this, we're seeing similar spikes of 503s due to upstream timeouts on 0.5.8 on production.
