Hello,
is there a problem with the DNS for all a-ads sub domains like ad.a-ads.com? At least with the DNS server from "Deutsche Telekom" I get the answer Host ad.a-ads.com not found: 3(NXDOMAIN) (since two days)
If I ask several other open DNS server like google or dyndns I always get a different IP. May this is ok because of the Round-robin DNS or similar technics. Everything else is working just the sub domains of a-ads not. Is there an issue with Deutsche Telekom? Because the DNS server from Arcor (another german internet provider) is answering.
