Hi
What is the distance between data centre zones in the UK South Region?
I would like to understand this before considering ASR from zone to zone instead of region to region.
Thanks
Reuben

I assume you are planning to enable Azure VM disaster recovery between availability zones as documented here - https://learn.microsoft.com/en-us/azure/site-recovery/azure-to-azure-how-to-enable-zone-to-zone-disaster-recovery
However, am not clear about this question "What is the distance between data centre zones in the UK South Region?"
Could you please re-phrase your question and elaborate a bit? -

https://learn.microsoft.com/en-us/azure/availability-zones/az-overviewIn the picture you can see the each av zone has its own datacenter, connected by fibre, what is the distance between these datacenter locations of UK South?
Thanks
Reuben
