Less than 1% of users are appearing in a huddle after the huddle has ended

Issue summary:
From December 7 at around 8:00 a.m. PST to December 13, 2021 at around 1:49 p.m. PST, some customers experienced issues with calls and huddles.

Following a service provider's outage, stale requests in our database prevented some users from joining new calls and huddles, while stale cached data caused some users to appear active in both.

We manually cleared stale calls and huddles from our backend, restoring functionality and dislodging stuck user statuses.
