The communication tool Slack has grown rapidly and become an important job tool in many workplaces. On Thursday evening, the service was hit by technical problems that made many users suddenly find it difficult to use the service.

Located down for Swedish users

At 08:00 on Friday morning, Slack was still down for many Swedish users.

Already on Thursday evening, Slack stated that the service has not been subjected to an attack – instead, the concerns are linked to DNS problems. The domain name system, DNS, is used, among other things, to translate domain names into IP addresses. For example, the domain name nyteknik.se can be translated to the IP address 52.208.207.74.

This is how you get Slacka to work

The DNS problem should be fixed, but the problems can remain because DNS addresses are cached in the networks and can therefore remain with the users for a while.

However, this can be remedied by manually entering the computer or mobile network settings, and changing the DNS to 8.8.4.4. or 8.8.8.8, writes The Verge.
