“We have identified the issue causing users to be unable to authenticate to the Zoom website and unable to start and join Zoom Meetings and Webinars, and we are working on a fix for this issue,” according to Zoom’s status page.

By early afternoon trading on the Nasdaq, Zoom was down more than 2%.

Zoom said the issue was resolved just after 1 p.m. ET.

Not everyone was affected by the outage. Some users reported that their Zoom calls were working. Others said they could not get into their regularly scheduled Zoom meetings.

Since the company’s massive spike in users, thanks to everyone working from home during the pandemic, Zoom has claimed some 300 million daily meeting participants.

Zoom didn’t immediately comment on the cause of today’s outage, but a spokesperson apologized for the downtime.
