FMCSA status

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.

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.

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.

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.

Yes. fleetfax reads the public federal datasets into our own database and updates that copy as FMCSA publishes, 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.
