Not sure if this is the right place to ask, but when trying to use the MacPython repo for pytables for building wheels, the builds are really slow (up to 45 min per instance). The issue is like:

```
Looking in links: https://nipy.bic.berkeley.edu/manylinux
Collecting numpy==1.9.3
/venv/local/lib/python2.7/site-packages/pip/_vendor/urllib3/util/ssl_.py:354: SNIMissingWarning: An HTTPS request has been made, but the SNI (Server Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this.

```

and the timeout before a retry seems to be pretty high.  I am wondering if this can be improved somehow.

The complete logs can be seen at e.g.: https://travis-ci.org/MacPython/pytables-wheels/jobs/505240399

Thanks!

You can drop the relevant URL.  That server lost it's certificate a while ago: https://github.com/MacPython/pytables-wheels/pull/18
