Klaus, I had a similar problem with my own websites. I could get anywhere but the server they resided on. Takes time to clear up.
In the meantime, try calling your ISP and ask if they'll give you a higher-level DNS server (well, two of them) to plug into your network settings. It worked for me. Generally, everyone with the ISP connects to certain DNS servers, but they have others they can give you that might work. But call them and ask if they can connect here. If so, get their DNS info. If not, ask them to look into it (after the 10 minutes it will take to convince them that ENWorld is, in fact, not down for the rest of the world).
