Seems to be an issue with:
a. Sites on Vox.x10hosting.com - IP 198.91.81.4
b. visiting from IP 88.**.**.** - ISP Telefonica de Espana
I have left a note for the Admins (they checked one of the complaints and it is not x10hosting blocking the member's IP) but if it is at your end, ie if Telefonica is blocking you from seeing Vox, it would probably go faster if any members with this problem contacted Telefonica and asked them to please lift the block.
