[Techtalk] LinkedIn Ubuntu connection weirdness

[Meryll Larkin]

Hey Wim,

It worked and maybe you can tell me how/why??? - because I'm baffled!

I went back to the Coffee Shop and verified that I could not reach any
second page deep level in LinkedIn.  

Then I changed my DNS in resolv.conf to Google's DNS, restarted my
networking services and behold:  I can now use LinkedIn from the Coffee
Shop!

The weirdest thing was that I couldn't get a traceroute to anywhere at all
after I switched DNS to Google - I reached the gateway (192.168.1.1 their
wireless router, I presume) and that was it.

Here is why I'm baffled:
  1.  I had already tried different DNS settings from the Coffee Shop
(although not Google), including the one that my girlfriend was using that
worked for her (on Windows).
  2.  The DNS that doesn't work for me to connect to LinkedIn at the Coffee
Shop is the same DNS that DOES work for me to connect to LinkedIn from home
(the coffee shop is about 5 miles from home).
  3.  Any why did traceroute stop working???

These must be very advanced networking mysteries.  Please teach me to point
me to good documentation!

Conor: attempting to connect to LinkedIn by IP address was one of the first
things I tried.  Did not work.
