AWS also uses Slack internally, so add that to the list of shit that can hit the fan if us-east-1/IAD goes down.

Don’t they also use Chime? It wouldn’t be a single point of failure.

To contribute to the tangled ball of messaging, slack also uses chime sdk to handle huddles

Wonder why huddles sound better compared to chime?

Lots of teams use Slack as well. Oddly enough, I didn't mind Chime as an end-user, but 6 years ago their API features were somewhat lacking.

Huh, I’m surprised they’re not all in on Chime.

It was all on Chime until the Pandemic. Then they moved to Slack.
