Description RolandUnger 2014-07-17 12:02:56 UTC 
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.
Comment 1 Sam Reed (reedy) 2014-07-17 12:05:07 UTC 
What ISP is it?

And you're using their DNS servers?
Comment 2 Sam Reed (reedy) 2014-07-17 12:11:48 UTC 
Can you also provide the output of dig for the various wikimedia hosts?

Thanks
Comment 3 RolandUnger 2014-07-17 12:29:24 UTC 
It is Hetzner.de, and I am using their servers, see http://wiki.hetzner.de/index.php/Hetzner_Standard_Name_Server/en

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!).
