Same issue with multiple domains: SERVFAIL errors on DNS resolution

Seems to be a bigger issue

#3

Perhaps @mvavrusa can shed some light here. Seems to be a lot of recent reports here with .de domains.

#4

Same for http://www.tvmovie.de and many more (that all work with the standard ISP DNS server).

Does anyone if CF is working on this?

#5

Sorry about that. It seems the united-domains.de nameservers went unreachable for some of our locations. I’ve sent an email to the technical contact for united-domains.de to see if there’s any network filters in place.
