Core Network DNS Issues

This week we have had several reported issues regarding the resolution of DNS and email being bounced. The issues have finally been isolated to one of our primary DNS servers and the records it holds. The server has had it records reloaded from a backup as corruption had occurred, which was difficult to trace due to the randomness of the reported problems and obtaining decent bounce messages.

For information this affected emails being delivered to our secondary mailscanner2 cluster service from some service providers. The exhaustive tests we have performed in the last 20 minutes are showing positive results. We will continue to monitor the situation and inform you of any further situations.

We apologise for any inconvenience caused.
