Issue summary:
From October 26th, 2021 at 9:28 a.m. PDT until November 1st, 2021 around 6:21 p.m. PDT, some Enterprise Grid customers may have noticed that messages with file attachments were temporarily disappearing.

This was an unexpected side effect of a recent change that was made to improve the efficiency of messages with file attachments. We deployed a fix for the misconfiguration, resolving the issue for all affected customers.

We're still investigating, but don't have any new information yet. We'll provide another update once we have more to share.

Some Enterprise Grid customers are seeing messages temporarily disappear. Refreshing (Ctrl / Command + Shift + R) may resurface the messages, but affected users may need to refresh more than once during the day.

We're sorry for the trouble. We're investigating, and we'll report back once we have next steps.
