Incident

Slow unfurls being experienced by all users.

Technical Summary:
On November 28th between 1:10pm (PT) and 4:33pm (PT), some customers experienced delays with parts of our service.

An issue occurred at 1:10pm (PT) that triggered a high amount of API calls, creating a backlog in one of our job queues. This caused delays for some customers with features that rely on the job queue, including unfurls, Slackbot messages, and "All Threads" or "All Unreads".

We worked through the backlog and deployed a fix which allowed the job queue to recover. The all clear was called at 1:38pm (PT).
