PyPI new user and new project registrations temporarily suspended.

This incident has been resolved.

Suspension has been lifted.

New user and new project name registration on PyPI is temporarily suspended. The volume of malicious users and malicious projects being created on the index in the past week has outpaced our ability to respond to it in a timely fashion, especially with multiple PyPI administrators on leave. While we re-group over the weekend, new user and new project registration is temporarily suspended.
