We rely on slack; we had multiple short outages last week. In slack terms, only a small number of teams were affected, but for us, that meant the whole company.

To be fair, the outages were short, and slack kept us in the loop. But the wider point is that such outages are possible with any SPOF, and if you work in a remote team, you should have a contingency plan to know which of those many alternatives you'll coordinate on when your primary service is down.
