Is python.org blocking traffic from the ibm.com domain?

Please contact me with details of the client machine trying to access
PyPI. We do block selected clients if they are accessing the
site in an excessive manner, but we don't (currently) block entire networks.

It's not normally the fear of Spam or a DOS that causes such blocking,
but just regular overloading, typically from a machine that fails to
honor robots.txt.
