Twitter turned off internal Slack, and staff claimed it didn't pay the bills.

Workers on the anonymous workplace messaging app Blind reported that Twitter had stopped paying for its use of the internal messaging service Slack, leading to the service being disabled.

Employees were so confused by the change that they didn't do any work on Friday because they couldn't even talk to each other, according to Platformer. Jira, the software that helps engineer’s ship code and monitors the development of new features, was also made unavailable to staff members.

Some workers coordinated their absences via email, while others took the whole day or two days off. The Slack service was not unavailable due to "routine maintenance," but Jira was temporary.

A Slack worker said, "There is no such thing as routine maintenance."

A representative from Slack has stated that the company has not disabled Twitter's channel or user accounts. When Slack performs maintenance, it usually lasts for a short period.

Unfortunately, we have yet to be able to keep up with our Slack payments. The current state of affairs has resulted in minimal effort from everyone. A Twitter worker said, "Penny wise, pound foolish."

To another, Slack's disappearance was the "last straw." Twitter did not respond right away to the news story.

However, on Friday, the platform was unavailable for a few users for a few minutes, and 55% of those who tried to access it via mobile device encountered difficulties. After a short delay, service was restored after the outage.
