Seems we have a resurgence of this with a vengeance. At the moment, we're getting a significant number of icmp/net-unreach responses for all regions in hpcloud trying to talk to pypi.openstack.org (and no sightings of similar issues between instances/tenants/regions within rackspace). This could imply network trouble in hpcloud, at rackspace's border, or on the backbone somewhere between them.

    Temporarily disable hpcloud in nodepool

    Failures indicate network trouble with all hpcloud regions reaching
    servers in rackspace, at least pypi.openstack.org in dfw.
