GitHub 也自己搞了一套管理多家 DNS 的程式...

StackOverflow 團隊發表完自己開發管理 DNS 的程式後 (參考「StackOverflow 對於多 DNS 商的同步方式...」),GitHub 也來參一腳:「Enabling DNS split authority with OctoDNS」。

可以看到 GitHub 用了兩家的系統 (AWSRoute 53Dyn 的服務):

;; AUTHORITY SECTION:
github.com.             172800  IN      NS      ns1.p16.dynect.net.
github.com.             172800  IN      NS      ns3.p16.dynect.net.
github.com.             172800  IN      NS      ns2.p16.dynect.net.
github.com.             172800  IN      NS      ns4.p16.dynect.net.
github.com.             172800  IN      NS      ns-520.awsdns-01.net.
github.com.             172800  IN      NS      ns-421.awsdns-52.com.
github.com.             172800  IN      NS      ns-1707.awsdns-21.co.uk.
github.com.             172800  IN      NS      ns-1283.awsdns-32.org.

GitHub 的 OctoDNS 用 YAML 管理:

octodns:
  type: A
  values:
    - 1.2.3.4
    - 1.2.3.5
zones:
  github.com.:
    sources:
      - config
    targets:
      - dyn
      - route53

有種當初 Dyn 被打趴後大家硬是想個解法的產物... @_@
