About USPS outages
The USPS website carries a load pattern unlike most commercial sites: Enormous, highly seasonal spikes around the December shipping deadlines, and a tracking system queried far more often than any other function.
The components that fail separately are package tracking, Click-N-Ship label purchasing, Informed Delivery, the ZIP code and address lookup tools, and the Business Customer Gateway. Tracking is the one people notice; a tracking number that returns "Status Not Available" is usually a scan that has not propagated rather than an outage. Scheduled maintenance is routine and typically falls in the early hours of Sunday morning Eastern time. The USPS site also applies bot mitigation aggressively, which can present as an access-denied page to VPN users and looks like downtime. There is no public status page.
What to do if USPS is not working for you
Is it them or you?
Our last check reached usps.com normally, from a different network, resolver and route than yours. If it is broken for you, the fault is most likely local or too narrow for a single probe to see. Run the check again now to confirm.
The first thing worth trying
Do not resubmit an order you are unsure about. Confirmation emails run late under load. Check your order history before trying again, or you will buy it twice.
How shopping & delivery services typically fail
Products browse perfectly, the basket fails. Queue pages appear. Orders may complete but confirmation emails arrive hours later, which causes a second wave of duplicate orders from people who assumed failure. The rest of the steps, and why this category breaks the way it does, are on our shopping & delivery status page, with more background in what an overload error looks like.
The link below unfurls into a live card showing the verdict, so whoever you send it to sees the evidence rather than your word for it.

USPS measured against its peers
How it compares with other shopping & delivery services
Over the last 30 days USPS ranks 5 of 7 shopping & delivery services we monitor, measured on recorded uptime. The category averages 100.0%, and USPS sits at 100.0%. The steadiest in this group is Amazon.
On speed, USPS answers our checks in about 200 ms against a category average of 201 ms - Faster than its peers. Response time is not availability, but a service drifting well above its own normal is often the first sign of trouble.
What the last 24 checks looked like
Across the most recent 24 checks, the quickest response was 69 ms and the slowest 413 ms, against a 30-day average of 200 ms. The chart above plots each one, so a widening spread is visible before it becomes an outage.
All figures are our own measurements, taken every 20 minutes from one network. What that can and cannot see is set out in the methodology, and every shopping & delivery service is listed on the category page.

An expired certificate stops browsers loading a site entirely while the server itself stays perfectly healthy, which is why we track it beside the uptime figure. Check it yourself.
USPS status: Common questions
Is USPS down right now?
USPS is up and responding normally. This page is refreshed by an automated check that runs every 20 minutes from an independent network, and by reports from visitors.
Why can I not reach USPS when you say it is up?
Because an outage can be partial. Our check runs from one network and asks for one page. Your problem may be regional, may affect only the mobile app, or may be local to your connection, DNS resolver or browser cache.
How reliable is USPS?
USPS has been reachable for 100.0% of the last 5 days we have measured, with 0 seconds of recorded downtime.
Does USPS have an official status page?
USPS does not publish a public status page, which is why independent monitoring and user reports are the only external signal available during an incident.
