Initial issue, posted 11/26/18, 12:08p:

We are experiencing an issue with Zoom video conferencing, which means a small number of meetings are disconnecting and some users are receiving an error message when trying to join a meeting. Zoom is working diligently to resolve the issue. We do not currently have an estimated repair time, although Zoom has identified the root cause and is working on a solution.  We will provide an update as soon as we know more.

We apologize for this disruption. Thank you for your patience.
