Incident

Slow link previews for all users

Technical Summary:
On December 10th, 2018 at 5:31pm PT, a workspace deletion caused a spike in our job queue as the backlog of data was cleaned up.

During this period, some users may have seen delayed link unfurls. We deployed a fix at 7:41pm PT and unfurls should be working as expected going forward.

We also implemented a change to job queuing to prevent this from happening again. If you experience any issues, please let us know at feedback@slack.com.

9:43 PM PST

We've been given the all-clear! Everyone should see their links preview at normal speeds now. Thank you for your patience through that.

8:16 PM PST

The team are still working to get to the bottom of these delayed link previews. Please hold tight.

8:03 PM PST

We're investigating reports of delays in previewing links. Apologies for this interruption to your day.
