Denmark card payment outage last night – Nets terminals down nationwide

Just a heads-up from Denmark: card payments went completely down last night, and it wasn’t just a local glitch. Stores all over the country were affected—POS terminals dead, ATMs offline, even online transactions failed in some cases.

The payment provider Nets has confirmed the outage, but says they still don’t know what caused it. According to their statement, there’s no sign of terrorism or foreign interference—just a mysterious, wide-scale failure in the core infrastructure.

Zettle also reported a "major outage" for card processing in Denmark around the same time. Everything was back online within before midnight, but the incident left a lot of people (and businesses) stranded, unable to pay or be paid.

This is one of the most cashless countries in the world, and it really showed how brittle the system can be. No clear cause. No clear prevention. Just… silence and fallback to cash (for those who had any).

Went down so hard that their status report page (https://www.nets.eu/dk-da/Pages/driftstatus.aspx) took 2 minutes to load a blank page. Later it started reporting an azure 504 after minutes

"Don't know why, but now it works. Problem solved"

Absolutely embarrassing. They need to be nationalised..

I am in Copenhagen for the first time and was wondering why there were 20+ people waiting in line at various ATMs last night. I think this explains it!
