Right..  I mentioned it because I would think it'd be rather difficult to confuse 'Nova sectors' with sectors on a disk.

Of those, I'd probably prefer 'Knots'.

Availability zones could be designated as a particular level of nesting of the overall zone design, such as a particular region, and users could specify the AZ they want their instance to be provisioned in. But a region might have several data centers, each of which could be a zone, and individual DCs could have several zones within them based on the physical layout of the building, or networking capacity, or because of incremental build out, or for any number of other reasons, none of which are relevant to a user.

So we should learn from that mistake and make sure we don't choose a replacement term that already has a common usage, such as shards segments or clusters.
