We have three Macs (one is a relatively new ibook) and Verizon Fios and can't get on to our school district's website (cbsd.org) with any of our Macs. I've tried downloading Firefox but that doesn't work either. Verizon said it's some kind of conflict with IP nos., and someone at Apple Support suggested I ask Verizon to update our router's software. We don't have trouble getting on any other sites. Has anyone experienced or heard of a similar problem?
