As also reported in the thread below, we too are having a number of Flows stuck in Queued now - some for over 1 hour. Clearly this there is a problem with Flow that is impacting multiple accounts. Yet the status.zoho.com for Flow still shows fully operational. 

Some of these Flows are VITAL to business operations. Occasional 10 minute delays are one things but multiple Flows queued for so long is a BIG problem.
