‘Terribly Sorry for the Disruption’ – Slack Gets Back Up after Hours-long Outage

Slack recovers after hours-long outage

Slack’s service is fully up and running after an outage hit its customer base globally.

The chat firm’s service checker had shown error messages across the board as companies around the world returned to work.

Service had largely returned to normal in the early hours of this morning, with the final issue – linked to calendar integrations – announced as fixed at 5:05am GMT.

“We're terribly sorry for the disruption, and we very much appreciate your patience,” Slack said.

“We will follow up with a summary as soon as we can”

Slack is yet to release any further information on what caused the outage, but has in the past published detailed accounts of what’s gone wrong.

In May an engineer published a blog titled “A Terrible, Horrible, No-Good, Very Bad Day at Slack”.

A second blog on this outage revealed that Slack’s protocols move it to a Zoom communication environment when it can no longer use its own service.

Slack’s status checker shows that its last outage before yesterday’s was in October.

The firm's share price dipped by nearly three per cent as it battled the outage yesterday.
