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.
Please see our FAQ on this question:
