Just a quick update, our ns2 and ns3 servers are currently still down and therefore the rest of our network is still considered at risk.
We are receiving continuing updates from our providers and they expect to have the situation fully assessed with the majority of systems back online within the next 4-5 hours. Please note that any damaged systems may take longer to restore, although the only data we currently do not have access to is copies of DNS zones stored on ns2 and ns3, which can easily be rebuilt if needed by copying data from the rest of our DNS cluster.
Thank you for your continuing patience.
