Description

The IP addresses resolution (DNS service) at Wikimedia does not work properly. The UNIX host commands gives no IP address.

Proper examples:

...:~$ host www.nytimes.com
www.nytimes.com is an alias for www.gtm.nytimes.com.
www.gtm.nytimes.com has address 170.149.168.130
...:~$ host www.spiegel.de
www.spiegel.de has address 62.138.116.3

But

...:~$ host wikivoyage.org
wikivoyage.org has address 208.80.154.224
wikivoyage.org has IPv6 address 2620:0:861:ed1a::1
wikivoyage.org mail is handled by 10 polonium.wikimedia.org.
wikivoyage.org mail is handled by 50 lead.wikimedia.org.
...:~$ host de.wikipedia.org
Host de.wikipedia.org not found: 3(NXDOMAIN)
...:~$ host de.wikivoyage.org
Host de.wikivoyage.org not found: 3(NXDOMAIN)

Our host provider confirms that this is a problem of Wikimedia.

What ISP is it?

And you're using their DNS servers?

Can you also provide the output of dig for the various wikimedia hosts?

Thanks

It is Hetzner.de, and I am using their servers, see http://wiki.hetzner.de/index.php/Hetzner_Standard_Name_Server/en

dig any wikimedia.org

Maybe this is helpful

This incident is resolved now (in part thanks to the debugging help from systems admins at Hetzner.de which the reporter put me in contact with!).
