At the time I was involved it did have an SLA, and was considered critical infrastructure for Genuitity customers. Once we started to deploy 4.2.2.1, we gave customers time to swap over, but we started turning off our existing DNS servers.
One reason we did it was that we kept having to deploy more servers, and getting customers to swing there hosts over to the new machines was all but impossible. With NetNews, and SMTP we used a Cisco Distributed Director. But we needed another solution for DNS. johno On Feb 14, 2010, at 5:20 PM, Patrick W.
