PostFinance outages and problems
In the past 24 hours we logged 52 user reports for PostFinance. Counting only the 15-minute windows with a spike big enough to count as an outage, that comes to 100.00% uptime for the day.

How to fix PostFinance not working
PostFinance is up on our end, so if it won't work for you, the problem is most likely on your side. Work through these in order:
Clear the e-finance login loop
If your login bounces you back to the start page every time, stale cookies are often the cause. Delete cookies for postfinance.ch in Chrome or Safari, then log in fresh. That fixes the loop for most people. Our PostFinance server status tracker reads operational with 52 reports in the last 24 hours, so if everyone asking 'is PostFinance down right now' sees the same loop, the fault sits with PostFinance and waiting it out is your only real option.
Update or reinstall the PostFinance App
Start with an update. Old builds break logins and payments whenever PostFinance changes something on its servers, so grab the newest version from the Play Store or the App Store. A white screen at launch or a crash at the payment step points to a corrupted install; delete the app and reinstall it. Complaints like 'PostFinance not working today' spike after every botched release, and searches for 'PostFinance outage today 2026' follow the same pattern, so check our 100.00% figure for the last 24 hours and the more than 24 hours ago gap since the last incident before you blame your phone.
Check your connection and DNS
Before you search 'is PostFinance down', test from a second network. Switch your phone from WiFi to mobile data and reload e-finance.postfinance.ch; if the page loads on data, your router or DNS is at fault. Flush the cache with 'ipconfig /flushdns' on Windows, or point your router at 1.1.1.1 and reload. Swisscom and Sunrise customers sometimes hit a routing hiccup that mimics a full bank outage. To answer 'is PostFinance working' with confidence, compare the official PostFinance network status page against our PostFinance down detector chart before you call the support hotline.

What happens when PostFinance goes down
PostFinance is the banking arm of Swiss Post, running card payments, transfers, e-bills, and the e-finance login for customers across Switzerland. Money waits for no bank.
When PostFinance goes down, the e-finance login hangs on a spinner, the app logs you out mid-session, card payments decline at the terminal, and transfers sit marked pending. Searches asking is PostFinance working spike within minutes, because a declined card tells you nothing about whose fault it is. We logged 52 of them in the past day; the usual culprits were login timeouts and app crashes.

How we track PostFinance
The status on this page comes from user-submitted problem reports for PostFinance, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for PostFinance, so a few complaints on a quiet day don't trigger anything, but a sudden jump well above normal does.
When reports climb well above normal, the status here changes to partial outage or major outage and the chart moves with it. PostFinance doesn't publish a public status page that we know of, so user reports are often the quickest sign that something is wrong on their side.
