Shipping software uptime ranked by how often each service breaks

Across the eleven shipping and logistics services StatusBird monitors, outage frequency is concentrated in one place: Shippo recorded 13 incidents and 1808 minutes of downtime in the last 90 days, while eight of the eleven recorded 100.0% uptime and zero major or critical incidents. ShipStation sat at 99.8% with a single incident, and Deliverr at 99.9% with two.

StatusBird checks each of these services every 2 minutes from its own probes, and every figure below comes from those readings over the 90 days ending October 13, 2026. The full method is on the methodology page.

Which shipping services went down most often in the last 90 days?

Ranked by incident count, not by uptime percentage:

The gap between the top and bottom of this table is not subtle. Eight services produced nothing StatusBird classified as major or critical. One service produced 13 separate events. Reliability history for each is at statusbird.io/reliability/shippo, shipstation, deliverr and easypost.

Why does incident frequency matter more than the uptime number here?

Shippo's 98.6% looks close to ShipStation's 99.8% if you only read the percentage. The operational experience is completely different. ShipStation had one bad morning: its incident started September 25, 2026 at 07:57 UTC and recovered at 12:11 UTC, a single block of 254 minutes. You lose one label-printing window, you recover, you move on.

Shippo's 1808 minutes arrived in 13 pieces with an average of 139 minutes each. Its two worst were long: 560 minutes starting July 30, 2026 at 04:42 UTC and 512 minutes starting October 1, 2026 at 04:42 UTC, both beginning in the early hours UTC and running through a European morning. But it also produced short hits that are easy to miss entirely: 8 minutes on September 24, 2026, 12 minutes on September 17, 2026, 30 minutes later on September 24, 2026, and 130 minutes on October 8, 2026.

Short, repeated failures are the ones that corrupt your records. A 12-minute label API failure does not announce itself. It leaves a handful of orders with no tracking number, a few duplicate label charges from retries, and a customer service queue you will not connect to an outage three days later.

What separates the services at the top from the ones at the bottom?

Two things show up in the data.

Carrier systems held, label aggregators did not. UPS, USPS, FedEx and DHL eCommerce all recorded 100.0% with zero incidents. The failures clustered in the software layer that sits between your store and those carriers. If your rates, labels and tracking all route through one aggregator, that aggregator is your single point of failure, not the carrier whose logo is on the box.

Recovery speed splits the middle of the table. Deliverr's two incidents averaged 62 minutes, less than half ShipStation's single 254 minutes and under half Shippo's 139 minutes average. Deliverr ended the window with more incidents than ShipStation but less total downtime, at 124 minutes against 254 minutes. If you are comparing vendors, ask for both numbers: how often, and how long each time.

How this showed up in the monthly totals

Shipping services led two of the last three monthly outage indexes. Shippo was the most affected service in July 2026, a month with 14 major or critical incidents and 22.1 hours of combined downtime across everything monitored. ShipStation was the most affected service in September 2026, which recorded 11 incidents and 12.6 hours of combined downtime. The month-by-month breakdown is on the outage index.

What should a store do with this ranking?

  1. Keep a second label path configured, not planned. If Shippo is your primary, create an EasyPost account and store the API key now. EasyPost recorded 100.0% and 0 incidents in the window. A fallback you have to sign up for during an outage is not a fallback.
  2. Stop retry loops before they double-charge you. During Shippo's 512 minutes on October 1, 2026, any automation set to retry label creation on failure kept firing for over eight hours. Pause the relevant Zapier or Make scenario, or switch your fulfillment automation to manual, before you start reprinting.
  3. Separate rates from labels. If live carrier rates at checkout come from the same vendor as your labels, set a flat-rate fallback in your store's shipping settings so checkout stays open when the rate call fails.
  4. Reconcile the short ones. After any incident under 30 minutes, export orders created in that window and check each has a tracking number. The 8-minute and 12-minute Shippo events in September 2026 are exactly the kind that pass unnoticed.
  5. Watch the near-term risk, not just history. As of today, Shippo is at an elevated risk level with a modelled 15.0% chance of a non-operational reading in the next 24 hours, and AfterShip is elevated at 17.7% despite its clean 90-day record. Live state is at statusbird.io/status/shippo and statusbird.io/status/aftership.

Does a clean 90 days mean a service is safe?

No. ShipBob, Flexport, UPS and USPS all finished the window at 100.0% with zero recorded major or critical incidents, which says they were stable across this particular 90 days. It does not promise the next 90. The useful read is relative: a service with 13 incidents has a pattern, and a service with 0 does not have one yet.

If you want to know when a shipping vendor stops responding rather than finding out from a customer asking where their tracking number is, StatusBird checks these services every 2 minutes and sends alerts by SMS, email, Slack, Teams or Discord. You can set up monitoring here.
