Ronaldsway flights to and from London and other UK airports have been suspended due to a flight data computer failure.
The Flight Data Computer Server at London ACC has failed - meaning that no traffic can be accepted into London airspace until 7pm.
Air traffic control organisation NATS is understood to have the issue.
Flights to and from Dublin, Manchester, Liverpool and Gatwick are currently suspended - flights to and from London City have been cancelled.
More information will be released as it becomes available.
