Discord vs Slack: reliability, measured
Current state and a 12-month uptime record for both, from RealUptime's own independent probes. This is a factual side by side, not a recommendation: it never ranks or scores either service, and states no opinion on which to choose.
Current state
We reached Discord from all 4 regions we check.
No outage recorded in the 24 days we have measured Discord (since Aug 8, 2026).
We reached Slack from all 4 regions we check.
No outage recorded in the 24 days we have measured Slack (since Aug 8, 2026).
Composed by the same rule each service's own page uses, with the same omission that page's dependency-stack view carries: user reports, public chatter and each vendor's own status-page claim are not read here, only our probes' own readings.
12-month record
Discord
Tracking Discord since Aug 8, 2026. In that time our probes detected no outage. Months before that date are not tracked and carry no figure.

Uptime here is the share of each month in which our probes had no outage open for Discord: two consecutive failed readings from a region opens one, the first clean reading closes it. Any detected outage counts, including one seen from a single region, and an outage that crosses midnight on the first of a month is counted in both months with its minutes split. User reports, public posts and Discord's own status page contribute nothing to these figures.
Slack

Every figure above is read from the same measurement each service's own page and 12-month history publish, never a separate calculation for this page. See Discord's full record or Slack's full record, or read how this check works.
