Incident

Trouble with Events API, notifications, unfurls, and threads

Technical Summary:

Starting on October 17, 2018 at 11:28 AM PT, some customers were seeing delays with certain features, including link unfurls, notifications, and integrations. After noticing a large increase in backlogged jobs, our engineering team began performing service restarts to process the delayed job queue. This restored functionality for all affected features at 9:25 AM PT on October 18th.
