Slack, an instant messaging and office productivity tool used by hundreds of major companies worldwide, reported late Wednesday morning that it had fixed a bug that had been causing technical issues with several of the application's features.
The issue had been keeping users from uploading files, making video calls, creating new direct messaging groups and reacting to messages with emojis in the early workday hours.
Slack first confirmed the problem at 5:50 a.m. ET. Downdetector, a crowd-sourced website that tracks outages on the internet, says that reports of issues with Slack began to spike at 8 a.m. ET — likely when millions of people logged on for work.
Slack was purchased by business software pioneer Salesforce in 2020. The service has become vital for many businesses in recent years, as companies have asked employees to work from home during the COVID-19 pandemic.
