Slack seems to have some issues because of that - I'm not sure if anyone is receiving messages, as it became completely silent for the last 15 minutes or so.
Sending and receiving messages works here, but editing them does not, it throws an error. Statuses such as "calling" also do not seem to be updated any longer.
Edit: Restarting Slack does update the edited messages.
I fail to understand how a big player like Slack can be impacted this way by a failure in a single AZ in a specific AWS region.
But at least the main feature (sending and displaying messages) is still working.
