Slack down: Office messaging chat app not working in the middle of the work day

Slack, the workplace messaging app, has stopped working. Users are finding themselves unable to send or receive messages – or really see anything at all. Slack's status page does not show the issue. But it is being widely reported across the internet and has been verified by The Independent. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.
