Is Slack down? Thousands say messages won’t send as site crashes worldwide

INSTANT messaging service Slack has crashed for thousands, hitting pause on workplace communications across the globe.

More than 5,000 users in the UK alone have reported issues with sending messages on the site since 10am this morning.

According to DownDetector, around 65 per cent of users say they can’t send messages.

The messages appear greyed out, as though they haven’t been delivered.

Over 20 per cent of users have also reported problems with receiving messages.

Meanwhile, 12 per cent say it isn’t just the website that has crashed – but the iOS and Android app too.

According to Slack’s server status website, the messenger is “up and running”.

However, thousands of users claim this isn’t the case.

The company last experienced 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.

The company has yet to comment on today’s (27 July) outage.

With the site crash occurring in the middle of the day, Slack users have taken to Twitter to rejoice in the occasion of being incommunicado at work.

“Slack seems down, everyone go play outside,” one user tweeted.

While others have complained about the company’s outage monitoring system, which appears to have failed.

“Slack is down globally but their downtime page shows that they’re up! What good monitoring system,” one Twitter user wrote.

Another wrote: “Everyone at work losing their minds because #Slack has crashed.”
