Adding Nova as affected project as well, from what we've observed so far
we cannot rule it out as a potential culprit in this whole saga.

** Also affects: nova

Title:
  SSH EOFError - Public network connectivity check failed

Status in OpenStack Neutron (virtual network service):
  New
Status in OpenStack Compute (Nova):
  New

Bug description:
  Was looking at this when investigating bug 1310852, so that might be a
  duplicate of this, but the "Public network connectivity check failed"
  message doesn't show up in the logs for that bug, so opening a new
  one.

  This is also maybe related to or regressions of bug 1194026 and/or bug
  1253896.

  The error in the console log:
