How to fix Zus not working
Zus 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:
Your browser tries to reach zus.pl over your own connection, right now. Nothing is sent to us or stored.
Reload and restart
Reload the page (Ctrl+F5, or Cmd+Shift+R on a Mac), or fully close the app and open it again.
Try another connection
Switch between Wi-Fi and mobile data. If it works on one and not the other, the problem is your network, not Zus.
Update the app
Install the latest version from the App Store or Google Play. Old versions can stop connecting after a server-side change.
While Zus is down: what to use instead
- mZUS app Try the mobile app if the website login or account pages fail, since some benefit and message tasks may still work there.
- ePUAP Use ePUAP to send an official letter when you need a dated submission and the main portal is not loading.
- ZUS call centre Call support if you need to check what channel fits your case or whether a visit is worth making.
- Local ZUS office Go to a branch for urgent pension, benefit, or contribution matters that cannot wait for the site to recover.
Problems at the same time as Zus
Since 3 November, all 3 of Zus's spikes in problem reports overlapped a spike at another service.
When several services get problem reports at once, something they share, such as a cloud host or a network, can be the real cause. Matching times alone do not prove it.

Tip: Zus doesn't list a public status page that we know of, so its help centre and the report chart on this page are the best places to check.
Put the Zus status badge on your site
Paste one of these into a web page, a blog post or a README. The badge shows the same status as this page, based on user problem reports. Browsers can keep a copy for up to 4 hours. It links back here.

How we track Zus
The status on this page comes from user-submitted problem reports for Zus, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for Zus, 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. Zus 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.
