Some users were experiencing intermittent network connection issues over the weekend. The OTISS servers themselves were up and stable, the problem was with internet connections at our hosting centre.

The OTISS servers will be shutdown tonight from 8:00pm for upgrade and maintenance.
Please login again in the morning.
