Ticker/announcement for Requester

Ticker/announcement for Requester

Is there anyway to show announcements in the requester part of the Service Desk?
 
Eg we have an externally hosted exchange solution, which has its issues, so when a user goes to log a call via the service desk area, they can see via an anouncement or ticker that IT knows there is an email issue currently.
 
Thus less duplicate calls .
 
thanks
