After yesterday's fiasco, I realized that how much I have taken things for granted. I was using ns1/ns2.theplanet.com for all my dns needs partly because I was proud to have associated my servers to The Planet brand name but it seems that when DLLSTX2 went down, it did bring down the ns1/ns2.theplanet.com DNS servers and although my servers were accessible via IP, they were not so via domain names. All my clients uses domain names access.
As such, I decided to move my DNS needs to a 3rd party service, dnsmadeeasy.com which seems great. I did the switch over when I got the entries all set up. Of course, when I do the whois on my domain names, it reflects the new DNS Servers but that is on record only and no reflection that the new DNS Servers are being used.
I knew there was something or somewhere I could use to check if all DNS queries are routed to the new DNS Servers but somehow I just cannot remember how.
This sudden loss of memory seems rather embarrassing and I was wondering if someone could point me to the right direction.
Thanks.
