Issue with APNIC DNS nameservers resolved

APNIC apologises for the interruption to our service on 6 May, 2008

APNIC started to receive reports that our DNS nameservers were not providing the expected answers for leaf node queries of delegated domains after we upgraded our DNS server software on Tuesday 6 May.

After initial investigation, it was determined that the upgraded software was the source of the problem. After contacting the vendor, several quick-fix solutions were attempted, to no avail.

At 13:00, Friday 9 May, APNIC rolled back to the previous version of the software, resolving the issue.

APNIC has advised the software vendor and requested escalation of the problem while working with them to review the upgrade and seek a clear resolution.

APNIC apologises for the interruption to our services.
