Is one of your bookings affected? Mine was and I saw that message last night but is now gone. When I want to change my booking, it's only allowing me date changes or refund with a penalty. And the best part is, I can't change to an earlier date or flight, only later flights. If they already screwed up, maybe allow more changes (e.g. an earlier flight or at the very least cancel without penalty). If your flight is canceled, they need to provide a refund without any penalties (or complain to MAVCOM to get a full refund).

Anything more than 5 hours will have to include meals and accommodation and if a flight is canceled, a full refund.
