Pro tip for anyone trying to check if a DNS record is working: do an NS lookup in cmd (Windows) in interactive mode. Set the server to the IP of a root DNS zone network (you can find these on Google) then enter that. Now do an nslookup for the domain you want.
- larrys 13y ago
  Actually no. The first step would be to go directly and query the nameservers set in the whois record (not the registrars which could be wrong but the registry). For xbox.com that is: Name Server: NS1.MSFT.NET Name Server: NS2.MSFT.NET Name Server: NS3.MSFT.NET Name Server: NS4.MSFT.NET Name Server: NS5.MSFT.NET

Technet DNS entries was gone for mediacom DNS servers about an hour ago in Northwest FL.
bencxr 13y ago
Based on what I have heard, the issue was caused by a bad active directory GPO that caused firewall rules to refuse DNS requests. Neither outlook/xbox/etc would have had any control over it. I heard that the issue has since been solved internally from 4.30 PST, though DNS changes often take time to propagate externally, taking TTL settings and ISP caches into consideration.

  They did release a new version of their Active Directory service in Azure yesterday. Wonder if its related.

Apparently it was due to Azure dying: http://www.theregister.co.uk/2013/11/21/azure_blips_offline_again/ http://www.theregister.co.uk/2013/11/21/azure_blips_offline_...

No, backwards. Azure outages were caused by DNS problems. http://gigaom.com/2013/11/21/another-bumpy-day-for-windows-azure/ http://gigaom.com/2013/11/21/another-bumpy-day-for-windows-a... https://twitter.com/scottgu/statuses/403670409406468096 https://twitter.com/scottgu/statuses/403670409406468096

Technet DNS entries was gone for mediacom DNS servers about an hour ago in Northwest FL.

Based on what I have heard, the issue was caused by a bad active directory GPO that caused firewall rules to refuse DNS requests. Neither outlook/xbox/etc would have had any control over it. I heard that the issue has since been solved internally from 4.30 PST, though DNS changes often take time to propagate externally, taking TTL settings and ISP caches into consideration.

They did release a new version of their Active Directory service in Azure yesterday. Wonder if its related.

It reminds me of the following quote - don't attribute to malice that you can attribute to incompetence.
