We and our customers are also experiencing this intermittent issue in both Service Desk and the customer portal, for open as well as closed incidents (see my previous post from 26/07 'Issues searching for ticket number in customer portal').
To give another example, this morning I was unable to link two incidents as the search returns 'Sorry, no results found' but the ticket I'm trying to link to is a current open ticket.
TB13 Sorry to hear about this. Have you been able to contact Customer Support with those examples so that they may investigate completely?
