Whatever service they are blocking with proably comes with a list of sites and flyertalk, yahoo, etc are all on it. I don't think anybody is typing them in individually.

Try going directly to the flyertalk.com IP address. Replace www.flyertalk.com in the address with 216.58.161.24

Lots of the blocking software is too stupid to check for IP address, it's only keying off the name.

HIPPA does not prevent you from plugging in laptops into a network. HIPPA prevents you from using certain information from that network. It's so totally amazing how overboard some places have gone in the name of HIPPA. If you plug in a laptop and don't go near any of the HIPPA protected stuff, then you aren't in violation. Even if you use the laptop to access information you can with your desktop, then you probably are still not in violation.

If you print it all out and take it home and post it on telephone poles in the neighborhood, that may be another story, but that isn't the fault of the laptop.
