It’s happened to all of us. You’re refreshing the page every ten minutes, hoping—praying—that the little progress bar finally moves from "Label Created" to "In Transit." Then, the unthinkable happens. The page crashes. Or worse, the status hasn't moved in four days, and you start wondering if your order fell off a truck in the middle of Nebraska.
When does tracker come back? It’s a question that usually hits when you're in a minor state of panic.
Tracking systems aren't magic. They're actually a fragile web of API calls, physical scans at dusty warehouses, and legacy software that sometimes dates back to the nineties. When a tracker goes down, it’s usually because one of those links in the chain snapped. Usually, it’s just a server refresh. Sometimes, it’s a global IT outage like the CrowdStrike incident that paralyzed logistics worldwide.
The Reality of System Downtime
Most people think "the tracker" is one single website. It isn't. When you check a tracking number on a site like AfterShip or 17Track, you’re looking at a middleman. These sites "scrape" or pull data from the carrier's internal system.
If USPS or FedEx is doing maintenance, the third-party site will show an error. Generally, these scheduled maintenance windows happen on Sunday nights between 12:00 AM and 4:00 AM EST. Why then? Because it’s the lowest volume of shipping activity. If you're looking at a screen during that window, just go to bed. It’ll be back by breakfast.
But what if it's not maintenance?
Why the "Pending" Status is a Lie
Sometimes the tracker is "up," but the data is dead. This is arguably more frustrating than a site crash. You see "Pending" for 72 hours. You start to think the system is broken. Honestly, the system is fine; the human isn't. A package only updates when a physical person or a high-speed sorter passes it under a laser. If a pallet is sitting in a "backlog" corner of a Chicago distribution center, that tracker isn't coming back to life until that pallet moves.

Weather events are the biggest "stealth" killers of tracking updates. If a blizzard hits Memphis—FedEx's main hub—the tracker doesn't say "Delayed by Snow." It just stops. It looks like it's broken. It's not. It's just waiting.
When Does Tracker Come Back After a Major Outage?
History gives us a pretty good roadmap here. When major logistics networks face a digital collapse, the recovery timeline is usually tiered.
- The "Ghost" Phase (0-6 hours): The website might load, but the data is "stale." It shows you where the package was yesterday, not now.
- The Restoration (6-12 hours): The main database comes back online. You can see your package, but the "Estimated Delivery" date is often wildly wrong.
- The Synchronization (12-24 hours): This is when the tracker truly "comes back." All the scans that happened while the system was down finally catch up and flood the system.
Back in 2023, when several major international couriers faced localized cyberattacks, some users didn't see a tracker update for nearly a week. It’s rare, but it happens. If you’re dealing with a cross-border shipment from a site like Temu or AliExpress, the "tracker" often goes dark for 5 to 7 days while the package is on a plane or clearing customs. In that specific niche, the tracker "comes back" once a local carrier like Pitney Bowes or PiggyBee scans it in the destination country.
Breaking Down the Carriers
Every carrier has its own rhythm for when their tracking data refreshes. You can't treat a DHL Express shipment like a Media Mail package.
USPS and the Infamous "In Transit to Next Facility"
We’ve all seen it. The dreaded "In Transit to Next Facility" message that repeats for three days. This is an automated placeholder. It means the system hasn't seen a physical scan in 24 hours, so it generates a generic update to keep the "Estimated Delivery" date from expiring. The real tracker comes back when the package hits a "Distribution Center" (NDC or VMF). If you see this, don't call them. They don't know where it is either until it hits the next laser.
FedEx and the Memphis "Black Hole"
FedEx is generally much more precise, but they have a "refresh" lag. If you’re wondering when the tracker comes back for a FedEx Ground shipment, check at 8:00 AM local time. That is when the local trucks are scanned for "Out for Delivery." If it doesn't update by then, it’s probably not coming that day.

UPS and Logical Scans
UPS uses "logical scans." This is a bit of a tech trick. If a trailer is scanned, the system "assumes" all 2,000 packages inside that trailer are also at that location. Sometimes, a package gets left behind on the dock. The tracker says it’s in Kentucky, but it’s actually still in California. The tracker "corrects" itself—or comes back to reality—once the individual box is scanned at the next hub.
What to Do When the Screen Stays Blank
If you’ve cleared your cache, tried a different browser, and the tracker still won't come back, you have to look at the "Last Known Location."
Is it at a "Customs" point? If so, the tracker isn't broken. It's in the hands of the government. Customs officials do not scan packages into the consumer-facing tracking system. They have their own internal logs. Your package is essentially in a legal purgatory where no tracker can reach it. This can last from 48 hours to three weeks.
Is it a "Last Mile" delivery? This is the most common reason people think their tracker is broken. Amazon or UPS drops a bag of 50 packages at a local post office. UPS marks it as "Delivered to Agent." The user thinks it's delivered to their house. It's not. The tracker will "come back" once the local mail carrier scans it into their specific route, which usually takes an extra 24 to 48 hours.
Technical Glitches vs. Physical Delays
Sometimes it’s just a bad API. Developers at these shipping companies are constantly pushing updates. If you see raw code or a "JSON Error" on the tracking page, the tracker is literally broken.
In these cases, the "tracker" usually comes back within two hours. These are high-priority tickets for IT teams because every minute the tracker is down, their customer service phone lines get slammed. Money talks. They fix those fast.

On the other hand, if the site looks fine but the date hasn't changed, that's a logistics delay. Total difference.
Steps to Take Right Now
Stop refreshing the same page. It won't help.
First, try a "multi-carrier" tracking tool. Sites like Ship24 or Postal Ninja often have access to more "raw" data than the simplified version you see on a retail site like Shopify or Amazon. They might show a "despatch" scan that the main site is hiding.
Second, check the carrier's "System Status" page. Most people don't know these exist. FedEx, UPS, and even Royal Mail have specific pages (often under "News" or "Service Alerts") that list active outages. If there’s a massive storm in the Pacific Northwest or a labor strike in France, they’ll list it there.
Third, wait for the "Golden Hour." For domestic shipping, most databases undergo a massive sync between 4:00 PM and 6:00 PM local time. This is when drivers return to the hubs and upload their handheld scanner data.
The Actionable Bottom Line
The tracker usually comes back once a physical scan occurs or a server maintenance window closes. If you've been waiting more than 48 hours without a single update:
- Check the "Shipment Facts" tab. Look for the "Travel History" rather than just the summary at the top. Sometimes the detailed logs show movement that the main status bar missed.
- Verify the service level. If you paid for "Economy" or "Standard," many carriers only scan the package at the beginning and the end. There is no "back" for the tracker because there was never a "middle."
- Sign up for SMS alerts. This is a pro move. SMS systems often operate on a different server than the web-based tracking maps. You might get a text update while the website is still showing an error message.
- Contact the sender, not the carrier. If the tracker doesn't come back after 5 business days, the sender is the one who has the contract with the carrier. They can initiate a "trace" which is a much deeper investigation than you can do as a recipient.
Tracking is a game of patience mixed with a bit of technological faith. Usually, the package is moving just fine; the data is just taking the scenic route to your screen. Give it until the next morning. Most of the time, that's all it takes for the "In Transit" light to turn green again.
To get the most accurate result, manually copy your tracking number and paste it directly into the carrier's primary website instead of clicking the link in your email. This bypasses potential "caching" issues where your phone might be showing you an old version of the page. If the primary site is down, wait two hours and try again. Use the time to double-check that your shipping address was entered correctly in your original order confirmation. Often, a "broken" tracker is actually a "Return to Sender" flag that hasn't fully updated yet. Stay calm, avoid the refresh button for an hour, and let the servers do their job.
