It’s not just you. Slack has been down for many people worldwide since late Thursday afternoon and some people are still struggling to access the messaging service via mobile app or even just on early Friday morning.

Slack says it’s a DNS issue and that your ISP may need to change its settings.

“We’re seeing some signs of improvement, and reloading Slack (Ctrl/Command + R) may allow Slack to load again. The issue is not resolved for everyone, however, and we’ll be back again once we have another update to share,” Slack tweeted.

Many people in countries on the other side of the globe, like Sweden and Australia, have been without Slack during their entire workday, leading to complaints from workers trying to get something done. Ironically, those same people aren’t even able to load to check for updates and are tweeting at the company.

“Our teams are aware and are investigating the issue. We know how important it is for people to stay connected and we are working hard to get everyone back up and running,” a Slack spokesperson told Gizmodo via email. “For the latest updates please keep an eye on @slackstatus and”
