Popular workplace messaging platform Slack resumed normal service Friday afternoon after widespread reports of disruptions by users.
On Slack's website, the company wrote around 1 p.m. EDT that many users had been unable to connect due to failure for the API, or application programming interface. Slack also said the "web servers are being overwhelmed at the moment."
About an hour later, the company began testing a fix, and by 2:24 p.m. EDT, Slack wrote on its website that it believed it has "addressed the cause of the terrible Slack outage this morning."
However, some lingering issues appeared to remain. The website said at 2:36 p.m. EDT that the fix had an impact on "serving file uploads and downloads" in that they may be very slow or fail.
According to the company's most recent update, 2.7 million users rely on the service. Workers who use Slack across the country expressed a mixture of joy and frustration at the disruption.
