Is ShipEngine down?
ShipEngine is operated by Auctane. This page keeps two claims apart: what ShipEngine reports about USPS, FedEx and UPS on its own status page, and what Shipzil's own rate request to ShipEngine's production API actually returned. Across 62 days of Shipzil's own checks, 17,361 of 17,545 rate requests to ShipEngine's production API (98.95%) returned a bookable rate, with a median response of 4,250ms and a 95th percentile of 8,768ms.
Shares incident reporting with ShipStation, so the two count as one independent source.

Measured rate checks
One fixed domestic US rate request to ShipEngine's production API every 5 minutes, over the last 24h. This measures one request path, not ShipEngine's overall speed.
8 checks ShipEngine did not answer within 15s · 0 we did not collect. A check we never ran is never counted against ShipEngine.

ShipEngine questions
- Is ShipEngine down right now?
- Shipzil reads ShipEngine's own status page every 5 minutes and, separately, sends a domestic US rate request to ShipEngine's production API. The current reading of both is at the top of this page and refreshes without reloading. A failed Shipzil check that ShipEngine has not acknowledged is shown as a failure it did not report, not as a declared outage.
- Is it ShipEngine or the carrier?
- Check whether other platforms report the same carrier. If only ShipEngine reports a USPS, FedEx or UPS problem, it is most likely ShipEngine's integration with that carrier. If platforms from two or more independent companies report it at the same time, it is more likely the carrier. ShipEngine and ShipStation are both run by Auctane, so agreement between those two counts as one source, not two.
- How reliable is the ShipEngine API?
- Across 62 days of Shipzil's own checks, 17,361 of 17,545 rate requests to ShipEngine's production API (98.95%) returned a bookable rate, with a median response of 4,250ms and a 95th percentile of 8,768ms. By ShipEngine's own incident reports, 90-day carrier uptime was USPS 100.00%, FedEx 99.24%, UPS 94.84%. The measured figure is one fixed request path from one account, not ShipEngine's overall performance; the reported figure only counts outages ShipEngine published.
