Assumptions

Results update as you type. Example figures are illustrative.

Your working data

Edit cells directly or import a CSV. Download “Input CSV” for the required column names. Up to 200 rows; scroll the table sideways for additional fields.

What this model includes

Relative minutes, not time zones. Each row replaces the affected-user count until the next event. User-impact minutes are not unique affected users.

Import and save safely

CSV imports use your current assumptions. Project files restore assumptions, rows and saved scenarios. No automatic saving: download a project before closing this page. Imports are limited to 10 MiB and 200 rows. Calculations run in your browser; the site’s advertising and analytics follow its privacy policy.

Using Service Incident Timeline

Build a relative incident timeline, measure response milestones and calculate user-impact minutes from affected-user segments.

  1. Enter the minute your observation ends.
  2. Add each event with its minute, type and the users affected from then on.
  3. Read the timings and impact picture beside your table, then download the timeline.

Example

The worked example includes Outage begins, Alert, On call responds, Partial recovery, Service restored.
Change the first observation ends at minute setting and compare the result with a saved baseline.

Questions & answers

What does Service Incident Timeline calculate?

Build a relative incident timeline, measure response milestones and calculate user-impact minutes from affected-user segments.

What are the important limitations?

Relative minutes, not time zones. Each row replaces the affected-user count until the next event. User-impact minutes are not unique affected users.

Can I continue my work later?

Yes. Save a project JSON file and reopen it with Import CSV / project. It contains the working data, assumptions and up to four scenarios. Nothing is saved automatically.

What CSV columns do I need?

event, minute, kind, affected, notes. Download Input CSV for a compatible example. CSV imports keep your current assumptions.

Are these example figures current industry benchmarks?

No. They are illustrative values to demonstrate the model. Replace them with figures appropriate to your situation.
