Since Slack's main business is chat, they have a pretty good incentive to get everything working again ASAP. Here's their SLA for "plus plan" and Enterprise plan: Our Plus plan Service Level Agreement (SLA) guarantees a 99.99% monthly uptime1 We’ve designed our SLA to be simple and transparent — based directly on the information we make publicly available on Slack’s System Status page. If we fall short of our 99.99% uptime guarantee, we’ll refund customers on the Plus plan 100 times the amount your workspace paid during the period Slack was down.
