Data freshness
Whether each live feed this site depends on is actually current right now, and when the underlying dataset behind everything else was last refreshed.
Live feeds
| Feed | Status | Last success | Detail |
|---|---|---|---|
| Loading… | |||
"Degraded" means the feed's own health check found a problem — a failed run, an unmatched code, or a schedule miss — not that the page showing that data is wrong. Every page that uses a feed marks its own data as stale when the feed is, rather than showing it as normal.
Bulk dataset
Everything that is not a live feed above — the fleet, fuel chain, ownership, company and design data — comes from a periodic snapshot, not a live poll. It changes only when the site is rebuilt against a newer release.
| Dataset | Source | Release |
|---|---|---|
| Reactor fleet, sites, ownership, companies, designs | CC BY 4.0 | August 2026 release |
