Some people are having trouble sending direct messages

Issue Summary:

On January 21, 2020 from 12:50 p.m. PST, some Slack customers experienced issues sending messages in direct message conversations. In particular, customers may have seen a "Slack couldn't send this message" error. These errors were a result of lag during one of our routine database changes, which caused significant delays to the data transfer. Once we resolved this delay, direct messages were delivered successfully once again and the issue was resolved at 5:57 p.m. PST.

For those affected, we're happy to report that we've fixed the issue with the direct message errors. We apologise for keeping you away from your work.
