The headline: outages are routine, not rare

32% of the services StatusBird monitors had at least one detected incident between March 16, 2026 and September 12, 2026. The typical disruption lasted about 255 minutes, which is long enough to lose a flash-sale hour, and short enough that most vendors never headline it. If your store runs on 84 services' worth of infrastructure, the question is not whether something will break this quarter. It's whether you'll know before your customers do.

What store owners should do with this

• Know your stack's weak links: check each service's grade on the reliability index.
• Estimate your exposure with the downtime cost calculator.
• Claim what you're owed: vendors with SLAs often owe credits after outages. StatusBird Business generates the claim from your incident log.
• Get alerted in 2 minutes, not 40: most owners discover outages from customer complaints.

Methodology: StatusBird polls each service's official status endpoint every 2 minutes. An incident is one continuous window of major or critical outage checks; minor degradation is tracked in the product but excluded from public availability figures. Durations are accurate to within the polling interval. Data reflects vendor-reported plus reachability-detected disruptions and may differ from vendors' own postmortems. Read the full methodology.
