Slack, the popular workplace instant message service, began experiencing “severe” lag on Wednesday afternoon, according to the company.
“The Slack Engineering team is currently investigating severe latency impacting all Slack services,” Slack wrote on its website just after 4 p.m. Pacific time. “We’ll provide an update as soon as we have more information to share and apologize for any inconvenience this is causing.”
A company dashboard showed problems impacting the service’s login, messaging, notification, search and API capabilities.
More than 3,000 problem reports about Slack had been logged by monitoring site Downdetector around the time of the announcement.
