Has Slack gone down before?
The company last reported experiencing issues with the site in late May, when some users were also unable to send and edit messages, load threads, join channels and create group DMs.
At the time, Slack discovered that a recent change in the websites coding had caused an “overwhelming impact” on its databases, which caused the issues.
“Once we rolled back the change and our databases were in a healthier state, the issue became resolved for impacted users,” the company announced at the time.
The issue took around an hour to resolve for most users.
However, some were still experiencing issues with messaging up to nine hours later, according to Slack’s server status logs.
