Dear Sirs,

We are a mobile telecom company in Brazil (TIM) and I am writing to  
ask a help to solve a problem or give us any feedback about the problem.

A customer from UNB (Universidade Nacional de Brasilia) complained  
that can not direct access the URL www.w3.org .

We analyzed the problem and for some unknown reason your site returned  
the reset to our IP address. Annexed the trace with the data.

Our company supplies the internet access to our customers with the  
following IP range.
189.64.0.0/15
189.116.0.0/15
187.46.0.0/15
187.82.0.0/16
189.67.128.0/17
186.196.0.0/16

The traceroute to www.w3.org ended to crusher.w3..org ..  Using  http://crusher.w3.org 
  the access to w3.org was successful.
