UPS has been highly reliable recently: StatusBird's independent monitoring recorded 100.0% availability and zero major incidents over the last 90 days.
Numbers alone do not tell you whether to worry, so this post also covers what actually breaks when UPS has problems and how to get warned early.
What is UPS?
UPS is one of the largest parcel carriers in the world, handling ground and express shipping for e-commerce orders across the US and internationally. Stores connect to UPS through shipping software or platform integrations to fetch live rates at checkout, purchase and print labels, schedule pickups, and give customers tracking updates.

What happens to your store when UPS goes down?
A UPS systems outage hits stores in two places. At checkout, live UPS rate lookups can fail, which depending on your setup either hides UPS options, shows fallback flat rates, or in the worst case blocks customers from completing checkout. In fulfillment, label purchasing through the UPS API fails, so orders pile up unshipped, and tracking pages stop updating, which drives a wave of where-is-my-order support tickets. Physical package movement is separate from the website and APIs, so parcels already in the network usually keep moving even when tracking looks frozen.
Typical symptoms during a UPS outage:
- UPS shipping options missing or erroring at checkout
- Label creation failing in your shipping software with UPS API errors
- Tracking numbers showing no movement or the tracking page not loading
- ups.com or the UPS developer APIs unreachable
- Spike in customer emails asking where their package is

Frequently asked questions
Are my packages actually stuck when UPS tracking stops updating?
Usually not. Tracking visibility runs on UPS's IT systems, which can fail independently of trucks and sorting facilities. Packages generally keep moving during a tracking outage, and scan history backfills once systems recover.
Can customers still check out if UPS rates fail?
That depends on your configuration. If UPS is your only live-rate option and there is no fallback, checkout can show no shipping methods and block purchases. Set up a backup flat rate or a second carrier now so a rate API failure never stops orders.
How this data is measured
StatusBird checks UPS's status every 2 minutes, around the clock, independently of the vendor. The availability figure counts major and critical outages only; minor degradation is excluded so numbers are not skewed by vendors that report small blips near-continuously. Grades run from A+ to F. See the live numbers on the UPS reliability page and current status on the UPS status page, or browse all 84 service grades.
Know before your customers do
StatusBird monitors UPS and 83 other services online stores depend on, plus your own storefront, every 2 minutes. When something goes down you get an SMS, email, or Slack alert with plain-English context, usually before the official status page catches up.
