Redirects

As for redirects, our browser reached this domain in two steps. The first redirect led to http://www.ziber.nl/, then it was forwarded to /pg-6457-7-74941/pagina/welkom.html, and finally we managed to open this domain. We strongly recommend that the redirects should be reduced, as the more redirects a site has, the slower it loads.

IP address

It is strongly recommended that the host server should be changed or the hosting provider should be requested to give a different (separate) IP address for this domain.
