title: Pip Install Timeout Issue
body: <p>I am trying to install pandas in my company computer.
  I tried to do</p>
  <pre><code>pip install pandas
  </code></pre>
  <p>but operation retries and then timesout.</p>
  <p>then I downloaded the package:</p>
  <p>pandas-0.22.0-cp27-cp27m-win_amd64.whl</p>
  <p>and install:</p>
  <pre><code>pip install pandas-0.22.0-cp27-cp27m-win_amd64
  </code></pre>
  <p>But I get the following error:</p>
  <blockquote>

  <p>I did the same with package: <code>pandas-0.22.0-cp27-cp27m-win_amd64.whl</code></p>
  <p>I also tried to use proxies:</p>
  <pre><code>pip --proxy=IND\namit.kewat:xl123456@192.168.180.150:8880 install numpy
  </code></pre>
  <p>But I am unable to get pandas.</p>
  <p>when I tried to access the site : <a href="https://pypi.org/project/pandas/#files" rel="noreferrer">https://pypi.org/project/pandas/#files</a> I can access it without any problem on explorer</p>
