In addition to alerts, dns administrators can now view test failures in the control panel. The detailed test failure logs are available for the preceding six months.

2010.05.01 - api and bulk record input

---

It is now possible to manage dns records programatically using a dns records management api. The api operates over the http protocol. Security is implemented using http digest authentication.

Bulk record input is available in the control panel. This facility accepts either csv text files, or zone files in the bind format. Zone files are translated to the csv equivalent for manual review before final commit.

Additional details may be found on the dns records api and bulk input page.

2009.09.07 - server additions

---

An additional authoritative dns server is now in service. It is located at the Equinix Ashburn data centre. As before, all servers are in geographically diverse locations. Colocation facilities are provided by our good friends at rackco.com.

The name of the new dns server appears in the control panel. It has also been forwarded in the daily usage reports.

To use this server, subscribers should add the new dns server name to the list of name servers that are authoritative for their domain at their domain registrar.

All existing dns records have already been populated at the new dns server. This was done after the new server was integrated into the backend. Therefore, there is no need to do anything in the edgedirector control panel. The dns records are fully synchronised and available. The only action required is to add the name server name to your domain records at the registrar.

The new server runs the same source code base as the existing servers with one significant difference. The difference is that the platform is now completely 64 bit executable code running on x64 hardware. In the future, all deployed servers will be 64 bit configurations.

The new server has been acting as a name server for our other domains prior to this announcement. There have been no observed errors or anomalies.

As in the past, we will continue to employ a rolling upgrade strategy. That is, only a single server will run the newest version of the code. This safeguards our clients from complete dns service outages due to software defects. There will always be dns services available from servers running a known good version.

In addition, all servers have archived copies of the recent versions that have run on that particular server. These archives are maintained to backout/rollback from version upgrades.
