VeriSign Naming and Directory Services (VNDS) currently generates new versions of the .com/.net zones files twice per day. VNDS is scheduled to deploy on September 8, 2004 a new feature that will enable VNDS to update the .com/.net zones more frequently to reflect the registration activity of the .com/.net registrars in near real time. After the rapid DNS update is implemented, the elapsed time from registrars' add or change operations to the visibility of those adds or changes in all 13 .com/.net authoritative name servers is expected to average less than five minutes. The rapid update process will batch domain name adds and domain name changes every few seconds. The serial number in the .com/.net zones' SOA records will increase with each batch of changes applied. As described in a message to the NANOG list in January , these serial numbers are now based on UTC time encoded as the number of seconds since the UNIX epoch (00:00:00 GMT, 1 January 1970).
