I host several Italian sites in a Virtual Private Server (VPS) located in Italy. At the moment, most of the domains are registered by the same provider, so all the nameservers are located in Italy too.
I want to switch to a new ISP, whose nameservers are located in the UK, USA and Canada, for domain registration, while keeping the same VPS hosting.
Could the DNS change have an impact on those websites' SEO?
Keep in mind that the actual host (the
A record in DNS) will remain the same.
