Link health alerts

A printed code is only as good as the page it opens. Websites move, shops change platforms and pages get deleted. Link health checks catch that for you.

How it works

• We check the destination of every website code about every 6 hours.
• One failed check can be a short hiccup, so we wait. After two failed checks in a row, we email you with the subject "Link issue: <your code name>".
• When the page works again, we send a second email to say it has recovered.
• The current status shows next to the code in your dashboard.

A check fails when the page does not answer within about 10 seconds or answers with an error, such as "page not found" or a server error.

What to do when you get an alert

1. 1Open the link from the email on your phone to see what scanners see.
2. 2If your website is down, fix it or ask whoever runs it. The code works again as soon as the page does.
3. 3If the page has moved or is gone, open the code in your dashboard, press "Edit content and design" and paste the new address.
4. 4Save. Scans go to the new page within seconds, and the printed code stays the same.

Which codes are checked

Website codes are checked, because they send scanners to a page outside our control. Hosted pages like PDFs, business cards and link lists live on our own servers, so they do not need it. WiFi codes never go online at all.
