Different signals
This is not a normal feature contest. Datadog's Updog and OutageDeck answer different questions during the same outage. Updog asks whether many real environments are seeing abnormal errors. OutageDeck asks what the provider has officially acknowledged, which products it named, and how its public account of the incident changed over time.
Disclosure: OutageDeck publishes this page. Updog facts were checked against Datadog's own product announcement and public dashboard as of August 2026. The source links are included so you can verify them yourself.
Updog
Updog uses aggregated, anonymized APM telemetry from thousands of Datadog customer environments. Its Bayesian model looks for abnormal error rates across customers and regions, which can surface systemic impact before a provider posts an incident.
OutageDeck
OutageDeck reads the official machine-readable feeds of 172cloud and SaaS vendors. It preserves the provider's own incident wording, affected services, timestamps, and source link instead of inferring impact from customer traffic.
Your telemetry
Neither public signal knows your tenant, credentials, request shape, or user path. Your own synthetic checks, logs, traces, and support reports are still the evidence that tells you whether the provider event affects your system.
| Question | Updog | OutageDeck |
|---|---|---|
| Primary evidence | Aggregated, anonymized APM telemetry across Datadog customer environments | Official provider status feeds and their published incident updates |
| Best question | Are users across many environments seeing abnormal provider errors? | What has the provider acknowledged, scoped, and updated publicly? |
| Detection timing | Can surface impact before the provider publishes an incident | Begins when the official feed changes, so acknowledgement can arrive later |
| Published coverage | 30+ SaaS APIs and 13 AWS services | 172 cloud and SaaS vendors with official feeds |
| History | Datadog Health Index history alongside provider status updates | Full provider incident timelines and independent 90-day uptime records |
| Public access | Free public dashboard without a Datadog account | Free public board, JSON API, RSS, badges, and MCP server without an account |
| Notifications | Targeted notifications in Datadog External Provider Status | Free email alerts, plus Slack, Teams, Discord, and webhooks on paid plans |
Datadog says Updog covers 30+ SaaS APIs and 13 AWS services, using aggregated anonymized telemetry and a Bayesian model. Datadog also published one DynamoDB example where its signal appeared 32 minutes before AWS updated its status page. Those are Datadog's claims and example, not a promise of a fixed lead time.
Outage alerts
Free email alerts for up to 5 providers. No card, live in about a minute. Paid plans add Slack, Teams, Discord, and webhook delivery across your whole stack, plus higher API quotas.
Updog's primary signal is observed impact inferred from aggregated, anonymized Datadog telemetry. OutageDeck's primary signal is what a provider has published on its official status feed. One can reveal widespread errors before an acknowledgement; the other records the provider's own scope, wording, and timeline.
Updog can be earlier because it does not wait for the provider to publish an incident. Datadog has published an example where it surfaced a DynamoDB degradation 32 minutes before AWS updated its status page. That is an example, not a guaranteed lead time for every provider or incident.
Use both when the dependency matters. Pair Updog or your own synthetic telemetry for observed impact with the provider's official feed for acknowledgement and scope. Agreement is strong upstream evidence. Disagreement tells you what to investigate next instead of forcing a false all-clear or outage verdict.
