System status & data freshness
A primary-source tracker is only as good as how current its data is. This page shows when each feed last updated and how it's monitored. If something is behind, you'll see it here.
Primary sources
How it's monitored
Automated checks run every 30 minutes, currently 46 of them. They compare what's stored against hard evidence. A recorded roll-call vote, for instance, proves a chamber sat that day, so a missing floor record for that day is treated as a gap to fix rather than assumed to be a recess. New legislation is expected within minutes of congress.gov publishing it, and any feed that stops updating raises an alarm by itself.
