Ya.com, a Spanish ISP, has just thought the internet is of its property, as for now, each page you visit that does not exist, like http://www.thispagereallydoesnotexist.com/ will get you redirected to their search page if you are using their service, obviouly abusing from DNS power. They may argue this is to help the user as "maybe" in the search page they'll find what they really were looking for, but as i have experienced in real life it's nothing bug disturbing, as i typed http://newbugs.kde.org/ (URL where i thought Dirk was doing his experiments for the new bugzilla) and ended in a ya.com page thinking "since when do we have hosting on ya.com pages?".
I've already sent them a mail asking for the removal of this service, if you are a ya.com user please do so too and let's see if we can get the internet to work again.
If you want to test the pain i feel use 126.96.36.199 as your DNS server.
