Hi Tobias,

Thanks for looking out.  I've spent a lot of time and I haven't
successfully identified much, I can add the following

- This issue is intermittent in CI
- It does *not* happen on any specific providers, I've seen it fail on
both OVH and Rackspace.
- Not *all* floating iP assignments fail, if you look at the logs, you
can see it attach a few successfully before failing

But yeah, I'm still quite at a loss and not having this coverage isn't fun.
