Nameservers with same IP, can cause high time to first byte?

postcd · 05-01-2014, 02:09 PM

Hello, when analysed domain by intodns.com i got:

Different subnets - WARNING: Not all of your nameservers are in different subnets
Different autonomous systems - WARNING: Single point of failure

Its because my nameservers are both pointed to same IP. How can this influence time to first byte? Meaning wait time when website load / resolve time. Can this be even 500 miliseconds slower? thx

Wrong question. Having name servers in different ASNs is about resilience not the speed of your line, server or web stack.
