Status
FMCSA infrastructure status
Live availability of the public FMCSA services that fleetfax and other carrier tools read from. We probe each one every 5 minutes and report what it returned.
fleetfax carrier lookups keep working during FMCSA outages by falling back to our own database. We refresh the federal record into our own copy daily, so a report loads from stored data even when a government service is not responding.
Dataset freshness
When FMCSA last published each dataset, and when fleetfax last ingested it. Freshness is bounded by the source: no tool can be fresher than the record itself.
Get outage alerts
We email you when an FMCSA service is down 10 or more minutes, and once more when it recovers. One recovery notice per outage, nothing else. Unsubscribe any time.

Questions
What is the QCMobile API?
QCMobile is the public FMCSA web service that returns a carrier's registration, operating authority, and safety record by USDOT or MC number. Many carrier-lookup tools, fleetfax included, read from it. When it is not responding, live lookups that depend on it can slow down or fail across the industry.
What is SAFER?
SAFER, the Safety and Fitness Electronic Records system, is the public FMCSA service that publishes a carrier's snapshot of registration and safety information. It is one of the most widely used public sources for checking a motor carrier. Like any government service, it has scheduled maintenance windows and occasional unplanned downtime.
What does degraded performance mean?
The service is answering, but not cleanly: some recent checks failed or ran slower than usual, or — for the QCMobile API — live fleetfax lookups saw errors even though our probes passed. One failed check is reported as degraded; we declare an outage only after two consecutive failures, so a single blip never reads as downtime. Degraded hours count as available in the uptime percentages.
Why does FMCSA infrastructure go down?
Federal systems go offline for routine reasons. The most common is a scheduled maintenance window, often overnight or on a weekend, when the agency updates its systems. Unplanned outages also happen, as they do with any large service. This page reports what each service returned to our probes. It does not diagnose the cause, and an absence of data is not by itself evidence of a problem.
Does fleetfax keep working during an FMCSA outage?
Yes. fleetfax reads the public federal datasets into our own database and refreshes them daily, so a carrier lookup on fleetfax is served from our copy of the record rather than a live call to FMCSA. When an FMCSA service is not responding, fleetfax carrier reports keep loading from that stored data.
We check each service every 5 minutes from our own infrastructure. An hour with no probe data shows gray, because we won't paint green over a gap. Degraded means the service answered but some checks failed or came back slow; we only call it an outage after two failed checks in a row. Degraded time still counts as available in the uptime numbers, so only failed checks lower them. fleetfax reads public FMCSA data and is not affiliated with, endorsed by, or connected to FMCSA or the U.S. Department of Transportation.
