Slack, the workplace chat app, is having some issues this morning, with messages failing to send on the service. Reports began spiking on DownDetector at around 5AM ET and the service’s status dashboard acknowledged the issues with a post at 5:35AM ET. It notes that “Users may be experiencing trouble with sending messages in Slack,” and says that the company is investigating the issue.

Slack elevated the status to an “outage” about 30 minutes later, at 5:57AM ET:

Slack experiencing an outage across the app. Users may be experiencing trouble with sending messages, using workflows and various other actions in Slack. We’re investigating and will let you know as soon as we know more. We appreciate your patience in the meantime.

Numerous users are reporting issues with Slack on Twitter which impacts browser-based Slack as well as the desktop and mobile apps. Some messages appear to be getting through when sent via the mobile apps but it’s inconsistent, with different Verge staffers seeing different results.

Although less common in recent months, Slack has experienced numerous outages like this throughout its history, which are typically resolved within a couple of hours or less. In the meantime, here’s a poem penned by my former colleague Chaim Gartenberg in 2018:

This is a post
To inform you
That Slack is down
It has been down for over an hour
If you use Slack for work
(Like I do)
You probably cannot connect
Your coworkers cannot hear you
Your GIFs will not send
Your messages, failed
“We’re working hard to isolate the issue.
Thanks for your patience!”
In the meantime
Maybe go for a walk
Call a friend
Eat a sandwich
Watch the World Cup
Slack will probably be back soon
And then this will all fade away
Like a dream
