Engineers have identified and resolved this issue. Our DNS sync system had a short outage which prevented zones getting pushed to our namservers and zones that have been manually set with extremely short EXPIRE values were dropped from the system. This impacted less than 1% of the zones in our system, but it is a good reminder that we recommend only lowering the TTL value of your zones as required. We strongly recommend leaving EXPIRE, REFRESH and RETRY at the default values of 604800, 10800, and 3600 respectively. We'll be updating the Control Panel to make this recommendation more obvious and explain the risks of lowering these values.
