Nordea customers may experience delays in receiving Kela benefits and salaries paid into their accounts on Tuesday, the bank has stated in a press release.
Nordea's service outage, which began on Sunday morning at 1am, had been due to end on Sunday evening but now enters a third day of disruptions.
The majority of services are running normally, but many are slower than usual. Transfer fees are currently disabled and online banking services may not display account and card transaction information.
Nordea has not yet announced when the service outage will be fully over, which the bank says is essential for maintenance of its IT systems.
