[2.7] bpo-36019: Use pythontest.net instead of example.com in network tests (GH-11941) by matrixise · Pull Request #12177 · python/cpython

I blocked access to example.com from my laptop using:
#11941 (review)

Without the test, test_urllib2net fails. With the change, test_urllib2net pass. Command "./python -m test -u all test_urllib2net".

I also ran "./python -m test -j0 -u all -r" with the change: SUCCESS.
