What happens to Telefonica's Speedy

Let's just say what is happening to users that Telefónica does not want to talk about: DNS poisoning. DNS you can read  by clicking here  to learn more about the subject, the telephone servers received a lot of wrong information from many domains and caused the requested pages from customers, went to other servers, which were not real servers, making DNS Telefónica, the most problematic that has ever existed.

If you use speedy, I recommend changing your provider, or at the very least, looking for other, safer DNS services, such as  OpenDNS  (in English), which is a free solution for resolving domain names.
